Key takeaways
Imipramine (Tofranil) and desipramine (Norpramin) are both tricyclic antidepressants (TCAs) used to treat depression, but they have some differences. Imipramine is available in two forms: imipramine hydrochloride and imipramine pamoate, while desipramine is available as desipramine hydrochloride. Imipramine can also be used to treat bedwetting in children, whereas desipramine is only approved for depression. The typical dosage for imipramine varies based on the form and the condition being treated, while desipramine is usually taken once daily. Both medications can cause side effects like sleepiness, dizziness, and weight gain, but desipramine has a higher risk of causing serotonin syndrome. Both medications can also cause severe withdrawal symptoms if stopped abruptly. Both medications are not first-choice options for depression due to their side effects and are available as lower-cost generics.
