Maprotiline is used to treat various types of depression and related anxiety. It may help improve mood and feelings of well-being. This medication belongs to a class of medications called tetracyclic antidepressants. It works by affecting the balance of certain natural chemicals (neurotransmitters) in the brain.

How should I take Maprotiline?

Take this medication by mouth, usually 1 to 3 times daily or as directed by your doctor. If you take it only once a day, take it at bedtime to reduce daytime sleepiness. The dosage is based on your medical condition and response to treatment.

To reduce your risk of side effects (such as drowsiness, dry mouth, dizziness), your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor’s instructions carefully.

Take this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
