Table of contents:

Aventyl is an antidepressant medication used in the treatment of depression. It contains an active ingredient called Nortriptyline. Nortriptyline belongs to the group of medications known as tricyclic antidepressants. It works in the central nervous system to elevate the mood of people with depression. It works by changing the balance of certain chemicals in the brain, such as serotonin and norepinephrine, which affect mood and emotions.

Aventyl is used to treat depression and may also be prescribed for other conditions like chronic pain, and anxiety disorders, or to help people quit smoking. It can be used to help manage and control the symptoms associated with depression, such as sadness, feelings of worthlessness, poor appetite, and difficulty sleeping.

Uses and Dosage

Aventyl is a medication that comes in tablet form and is taken by mouth as prescribed by your doctor, usually between 1 to 4 times daily. Your medical condition and response to treatment will determine the accurate dosage, and to reduce the risk of side effects like dry mouth and dizziness, your doctor may direct you to start with a low dose and gradually increase it.

Take Aventyl regularly to get the maximum benefit from it. To help you remember, take it at the same time(s) each day. Do not alter your dose, frequency, or duration of use without consulting your doctor, as your condition may not improve faster, and your risk of side effects may increase.

The recommended adult dose ranges from 30 mg to 150 mg daily in divided doses. The usual adult starting dose is 25 mg 3 or 4 times daily. The dosage can be increased until the desired effect is achieved.
