This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy.

Older adults may be more sensitive to the side effects of this drug, especially bleeding or loss of coordination. Older adults may also be more likely to develop a type of salt imbalance (hyponatremia), especially if they are also taking "water pills" (diuretics). Loss of coordination can increase the risk of falling.

Children may be more sensitive to the side effects of this drug, especially loss of appetite and weight loss. Monitor weight and height in children who are taking this drug.

This medication is not recommended for use during pregnancy. It may harm an unborn baby, and babies born to mothers who have used it during the last 3 months of pregnancy may sometimes develop withdrawal symptoms such as feeding/breathing difficulties, seizures, muscle stiffness, or constant crying. However, since untreated mental/mood problems (such as depression, panic attack, obsessive-compulsive disorder, anxiety) can harm a pregnant woman and her unborn baby, do not stop taking this medication unless directed by your doctor. Instead, ask your doctor if a different medication would be right for you. If you are planning pregnancy, become pregnant, or think you may be pregnant, tell your doctor right away.
