Amitriptyline hydrochloride (Elavil®) is a prescription medication used to treat depression. The drug comes in tablet form and is taken one to three times a day. There are six strengths of amitriptyline available, ranging from 10 mg to 150 mg tablets.
The strength and dosage that is right for you will depend on several factors, such as your age, the medical condition being treated, and other medications you are taking. In general, amitriptyline should be started at a low dose (especially in the elderly) and increased slowly if necessary. The maximum dose for most people is 150 mg total daily. People who are in the hospital can take up to 300 mg per day.
