      Atorvastatin

      Potential Negative Interaction

      A study of 37 people with high cholesterol treated with diet and HMG-CoA reductase inhibitors found blood vitamin A levels increased over two years of therapy. Until more is known, people taking HMG-CoA reductase inhibitors, including atorvastatin, should have blood levels of vitamin A monitored if they intend to supplement vitamin A.

      Isotretinoin

      Potential Negative Interaction

      Although little is known about how isotretinoin interacts with real vitamin A, the two are structurally similar and have similar toxicities. Therefore, people taking isotretinoin should avoid vitamin A supplements at levels higher than typically found in a multivitamin (10,000 IU per day).

      Minocycline

      Potential Negative Interaction

      A 16-year-old girl developed headaches and double vision following treatment for acne with vitamin A and minocycline. These side effects disappeared once the compounds were discontinued. More research is needed to determine whether the symptoms could have been caused by an interaction between vitamin A and the drug.

      Thioridazine

      Potential Negative Interaction

      A review of people taking thioridazine showed that they had higher blood levels of vitamin A than did individuals not using the drug. More research is necessary to determine whether taking vitamin A supplements with thioridazine might cause dangerously high vitamin A levels. Until more is known, people taking thioridazine should exercise caution with vitamin A supplementation and be alert for side effects such as bone pain, headaches, dry scaly skin, and hair loss.

      Tretinoin

      Potential Negative Interaction

      Large amounts of vitamin A can cause side effects, and oral tretinoin can cause similar side effects. Combining vitamin A with oral tretinoin is likely to increase the risk of side effects. People taking oral tretinoin should probably not take more than 10,000 IU of supplemental vitamin A per day.

      Replenish Depleted Nutrients

      Anticonvulsant drugs can occasionally cause birth defects when taken by pregnant women, and their toxicity might be related to low blood levels of vitamin A. One controlled study showed that taking multiple anticonvulsant drugs results in dramatic changes in the way the body utilizes vitamin A. Further controlled research is needed to determine whether supplemental vitamin A might prevent birth defects in children born to women on multiple anticonvulsant therapy. Other research suggests that ingestion of large amounts of vitamin A may promote the development of birth defects, although the studies are conflicting.

      Bile acid sequestrants, including colestipol, may prevent absorption of folic acid and the fat-soluble vitamins A, D, E, K. People taking colestipol should consult with their doctor about vitamin malabsorption and supplementation. People should take other drugs and vitamin supplements one hour before or four to six hours after colestipol to improve absorption.

      Animal studies suggest calcium and zinc may be depleted by taking cholestyramine, another bile acid sequestrant. Whether these same interactions would occur with colestipol is not known.

      Mineral Oil

      Replenish Depleted Nutrients

      Mineral oil has interfered with the absorption of many nutrients, including beta-carotene, phosphorus, potassium, and vitamins A, D, K, and E in some, but not all, research. Taking mineral oil on an empty stomach may reduce this interference. It makes sense to take a daily multivitamin-mineral supplement two hours before or after mineral oil. It is important to read labels, because many multivitamins do not contain vitamin K or contain inadequate (less than 100 mcg per day) amounts.

      In one well-controlled study, taking orlistat for six months resulted in reduced blood levels of vitamins A and D, though levels for most individuals remained within the normal range. However, a few people developed levels low enough to require supplementation. Other studies have shown that taking orlistat had no affect on blood vitamin A levels. Although additional research is needed, the current evidence suggests that individuals taking orlistat for more than six months should supplement with vitamins A and D.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research.Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but it clearly shows that antioxidants need not be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

    • Vitamin A, Vitamin C, and N-Acetyl Cysteine

      Capecitabine

      Needs Explanation

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

    • Vitamin A

      Capecitabine

      Needs Explanation

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Cisplatin

      Needs Explanation

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Cortisone

      Needs Explanation

      In some people, treatment with corticosteroids can impair wound healing. In one study, topical or internal vitamin A improved wound healing in eight of ten patients on corticosteroid therapy. In theory, vitamin A might also reverse some of the beneficial effects of corticosteroids, but this idea has not been investigated and no reports exist of such an interaction in people taking both vitamin A and corticosteroids. People using oral corticosteroids should consult with a doctor to determine whether improved wound healing might outweigh the theoretical risk associated with concomitant vitamin A use.

      Although blood levels of vitamin A appear to increase during dexamethasone therapy—most likely due to mobilization of the vitamin from its stores in the liver—evidence from animal studies has also indicated that corticosteroids can deplete vitamin A from tissues.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Desogestrel-Ethinyl Estradiol

      Needs Explanation

      A review of literature suggests that women who use oral contraceptives may experience decreased vitamin B1, B2, B3, B12, C, and zinc levels. Oral contraceptive use has been associated with increased absorption of calcium and copper and with increased blood levels of copper and vitamin A. Oral contraceptives may interfere with manganese absorption. The clinical importance of these actions remains unclear.

      Dexamethasone

      Needs Explanation

      In some people, treatment with corticosteroids can impair wound healing. In one study, topical or internal vitamin A improved wound healing in eight of ten patients on corticosteroid therapy. In theory, vitamin A might also reverse some of the beneficial effects of corticosteroids, but this idea has not been investigated and no reports exist of such an interaction in people taking both vitamin A and corticosteroids. People using oral corticosteroids should consult with a doctor to determine whether improved wound healing might outweigh the theoretical risk associated with concomitant vitamin A use.

      Although blood levels of vitamin A appear to increase during dexamethasone therapy—most likely due to mobilization of the vitamin from its stores in the liver—evidence from animal studies has also indicated that corticosteroids can deplete vitamin A from tissues.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A review of literature suggests that women who use oral contraceptives may experience decreased vitamin B1, B2, B3, B12, C, and zinc levels. Oral contraceptive use has been associated with increased absorption of calcium and copper and with increased blood levels of copper and vitamin A. Oral contraceptives may interfere with manganese absorption. The clinical importance of these actions remains unclear.

    • Vitamin A

      Ethinyl Estradiol and Levonorgestrel

      Needs Explanation
      A review of literature suggests that women who use oral contraceptives may experience decreased vitamin B1, B2, B3, B12, C, and zinc levels. Oral contraceptive use has been associated with increased absorption of calcium and copper and with increased blood levels of copper and vitamin A. Oral contraceptives may interfere with manganese absorption. The clinical importance of these actions remains unclear.

    • Vitamin A, Vitamin C, and N-Acetyl Cysteine

      Etoposide

      Needs Explanation

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Needs Explanation

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      A review of literature suggests that women who use oral contraceptives may experience decreased vitamin B1, B2, B3, B12, C, and zinc levels. Oral contraceptive use has been associated with increased absorption of calcium and copper and with increased blood levels of copper and vitamin A. Oral contraceptives may interfere with manganese absorption. The clinical importance of these actions remains unclear.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A review of literature suggests that women who use oral contraceptives may experience decreased vitamin B1, B2, B3, B12, C, and zinc levels. Oral contraceptive use has been associated with increased absorption of calcium and copper and with increased blood levels of copper and vitamin A. Oral contraceptives may interfere with manganese absorption. The clinical importance of these actions remains unclear.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Methylprednisolone

      Needs Explanation

      In some people, treatment with corticosteroids can impair wound healing. In one study, topical or internal vitamin A improved wound healing in eight of ten patients on corticosteroid therapy. In theory, vitamin A might also reverse some of the beneficial effects of corticosteroids, but this idea has not been investigated and no reports exist of such an interaction in people taking both vitamin A and corticosteroids. People using oral corticosteroids should consult with a doctor to determine whether improved wound healing might outweigh the theoretical risk associated with concomitant vitamin A use.

      Although blood levels of vitamin A appear to increase during dexamethasone therapy—most likely due to mobilization of the vitamin from its stores in the liver—evidence from animal studies has also indicated that corticosteroids can deplete vitamin A from tissues.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A new formulation of selenium (Seleno-Kappacarrageenan) was found to reduce kidney damage and white blood cell–lowering effects of cisplatin in one human study. However, the level used in this study (4,000 mcg per day) is potentially toxic and should only be used under the supervision of a doctor.

      This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Needs Explanation

      In some people, treatment with corticosteroids can impair wound healing. In one study, topical or internal vitamin A improved wound healing in eight of ten patients on corticosteroid therapy. In theory, vitamin A might also reverse some of the beneficial effects of corticosteroids, but this idea has not been investigated and no reports exist of such an interaction in people taking both vitamin A and corticosteroids. People using oral corticosteroids should consult with a doctor to determine whether improved wound healing might outweigh the theoretical risk associated with concomitant vitamin A use.

      Although blood levels of vitamin A appear to increase during dexamethasone therapy—most likely due to mobilization of the vitamin from its stores in the liver evidence from animal studies has also indicated that corticosteroids can deplete vitamin A from tissues.

      Needs Explanation

      Anticonvulsant drugs can occasionally cause birth defects when taken by pregnant women, and their toxicity might be related to low blood levels of vitamin A. One controlled study showed that taking multiple anticonvulsant drugs results in dramatic changes in the way the body utilizes vitamin A. Further controlled research is needed to determine whether supplemental vitamin A might prevent birth defects in children born to women on multiple anticonvulsant therapy. Other research suggests that ingestion of large amounts of vitamin A may promote the development of birth defects, although the studies are conflicting.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Needs Explanation

      A study of 37 people with high cholesterol treated with diet and HMG-CoA reductase inhibitors found blood vitamin A levels increased over two years of therapy. Until more is known, people taking HMG-CoA reductase inhibitors, including simvastatin, should have blood levels of vitamin A monitored if they intend to supplement vitamin A.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

      Needs Explanation

      This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.

      A controlled French trial reported that when postmenopausal late-stage breast cancer patients were given very large amounts of vitamin A (350,000–500,000 IU per day) along with chemotherapy, remission rates were significantly better than when the chemotherapy was not accompanied by vitamin A. Similar results were not found in premenopausal women. The large amounts of vitamin A used in the study are toxic and require clinical supervision.

      Needs Explanation

      This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.

      Chemotherapy can injure cancer cells by creating oxidative damage. As a result, some oncologists recommend that patients avoid supplementing antioxidants if they are undergoing chemotherapy. Limited test tube research occasionally does support the idea that an antioxidant can interfere with oxidative damage to cancer cells. However, most scientific research does not support this supposition.

      A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

      A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but neither does it show that antioxidants should be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.
