title: Drugs that cause weight gain.
abstract: Among drugs which cause weight gain, the tricyclic antidepressant medications are a drug class producing persistent and problematic body weight gain in many treated patients. Major depressive illness is often associated with reductions in appetite and body weight, and treatment with antidepressants effectively restores mood, appetite and weight. However, a frequent complaint of patients treated with tricyclic drugs is of excessive and unwanted weight gain, often times resulting in medication noncompliance. The incidence of weight gain during acute and chronic treatment with different, frequently prescribed antidepressant drugs will be reviewed, as will the possible mechanisms by which such drugs alter caloric intake and expenditure, contributing to drug-induced weight gain.
