LEVOTHYROXINE (lee voe thye ROX een) and LIOTHYRONINE (lye oh THYE roe neen) Porcine, also known as Dessicated Thyroid, is a combination of 2 thyroid hormones. This medicine can improve symptoms of thyroid deficiency such as slow speech, lack of energy, weight gain, hair loss, dry skin, and feeling cold.

NATURE-THROID Lifestyle Interactions

Levothyroxine 38mcg, Liothyronine 9mcg, Oral tablet

Enteral Feedings

· Severity: Severe

· Notes for Consumers: It is best to take Thyroid hormones on an empty stomach. To avoid an interaction with liquid nutrition products, take Thyroid hormones 1 hour before tube feedings or nutritional supplement beverages.

· Notes for Professionals: Certain foods, beverages, and enteral feedings can inhibit the absorption of thyroid hormones. To minimize the risk of an interaction, thyroid hormones should be administered on an empty stomach with a glass of water at least 30 to 60 minutes prior to food or enteral feedings. Foods that may decrease thyroid hormone absorption include soybean flour and soy-based infant formulas or enteral feedings, as well as high fiber diets, cottonseed meal, and walnuts. In addition to decreasing the oral absorption of thyroid hormones, limited data indicate that soy containing foods and supplements may also influence thyroid physiology. Concentrated soy isoflavones (e.g., genistein and daidzein) may interfere with thyroid peroxidase catalyzed iodination of thyroglobulin, resulting in a decreased production of thyroid hormones and an increased secretion of TSH endogenously. More studies are required to assess the exact mechanism of this interaction. Caution should be used in administering soy isoflavone supplements concurrently with thyroid hormones. Limited data show that coffee has the potential to impair T4 intestinal absorption. In one report, T4 intestinal absorption was evaluated after the administration of 200 mcg L-thyroxine (L-T4) swallowed with coffee/espresso, water, or water followed 60 minutes later by coffee/espresso. Researchers found that administration with coffee/espresso significantly lowered average serum T4 (p<0.001) and peak serum T4 concentrations (p<0.05) when compared to L-T4 taken with water alone. Coffee/espresso taken 60 minutes after L-T4 ingestion had no significant effect on T4 intestinal absorption. It is prudent to remind patients that thyroid hormones should be separated from food and beverages (other than water), including coffee, by at least 30 to 60 minutes.

Food

· Severity: Severe

· Notes for Consumers: It is best to take Thyroid hormones on an empty stomach. Food can limit the absorption of these hormones from the stomach. Examples of interacting foods include, but may not be limited to, soy protein, soy infant formulas, high fiber foods, liquid nutrition shakes, and walnuts. To avoid interactions with food, take Thyroid hormones 1 hour before any food. To avoid an interaction with liquid nutrition products, take Thyroid hormones 1 hour before tube feedings or nutritional supplement beverages.
