Why is this medication prescribed?
Nortriptyline is used to treat depression. Nortriptyline is in a group of medications called tricyclic antidepressants. It works by increasing the amounts of certain natural substances in the brain that are needed to maintain mental balance.
How should this medicine be used?
Nortriptyline comes as a capsule and an oral liquid to take by mouth. It is usually taken one to four times a day and may be taken with or without food. Take nortriptyline at around the same times 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 nortriptyline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of nortriptyline and gradually increase your dose.
Continue to take nortriptyline even if you feel well. Do not stop taking nortriptyline without talking to your doctor. If you suddenly stop taking nortriptyline, you may experience withdrawal symptoms such as headache, nausea, and weakness. Your doctor will probably want to decrease your dose gradually.
