This medication is used to treat depression. Treating depression can improve your mood and sense of well-being and allow you to enjoy everyday life more.Amoxapine is a tricyclic antidepressant. It works by restoring the balance of natural chemicals (neurotransmitters) in the brain. Because amoxapine has some effects that are similar to those of major tranquilizers, it may work better in patients who have agitation or anxiety along with depression.
How to use Amoxapine
Take this medication by mouth with or without food as directed by your doctor, usually 1 to 3 times daily. To lessen side effects, amoxapine may be started at a low dose and slowly increased as your body gets used to it. Follow your doctor's instructions carefully. If you are taking this medication once daily, it is usually taken at bedtime to prevent daytime drowsiness. The dosage is based on your medical condition, age, and response to treatment.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. This medication does not work right away. It may take up to two weeks before you experience the full benefits.
Keep taking this medication even if you feel well. Do not suddenly stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is abruptly stopped. Your dose may need to be gradually decreased.
Inform your doctor if your condition does not improve or if it worsens.

Antidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition.
Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed.
