WHY is this medicine prescribed?

Desipramine is used to treat depression. Desipramine is in a class of medications called tricyclic antidepressants. It works by increasing the amounts of certain natural substances in the brain that are needed for mental balance.

HOW should this medicine be used?

Desipramine comes as a tablet to take by mouth. It is usually taken one or more times a day and may be taken with or without food. Take desipramine at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take desipramine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of desipramine and gradually increase your dose.

It may take 2 to 3 weeks for you to feel the full benefit of desipramine. Continue to take desipramine even if you feel well. Do not stop taking desipramine without talking to your doctor. If you suddenly stop taking desipramine, you may experience withdrawal symptoms such as nausea, headache, and weakness. Your doctor will probably want to decrease your dose gradually.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of the reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily.
