Amitriptyline belongs to a family of medications known as tricyclic antidepressants. It is used to treat depression. It works in the central nervous system (CNS) to elevate the mood of people with depression. It is believed to work by keeping the balance of natural chemicals (neurotransmitters) in the body, namely serotonin and norepinephrine. It may start to work within 3 to 4 days, but it may take up to 30 days to see the full effects.

The usual starting dose of amitriptyline for depression in adults is 25 mg 3 times a day. The dose of amitriptyline is usually started low and increased slowly as prescribed by the doctor until the medication is at a dose that is appropriate and effective. After symptoms improve, the dose may be reduced to the lowest amount that will relieve symptoms. The usual maintenance dose of amitriptyline for adults ranges from 50 mg to 100 mg per day in divided doses. For some people, the daily dose can be given as a single dose, preferably at bedtime.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Heart diseases: Tricyclic antidepressant medications such as amitriptyline can cause abnormal heart rhythms, particularly when taken in high doses.
