Available in tablet form, amitriptyline hydrochloride (Elavil®) is a drug used for the treatment of depression. The brand-name product (Elavil) is no longer available. However, generic versions are widely available in a number of different strengths, ranging from 10 mg to 150 mg. Common side effects include drowsiness, dizziness, and constipation.
When determining your dosage of amitriptyline tablets, your healthcare provider will take into account many factors, such as:
- The medical condition being treated (sometimes amitriptyline is used "off-label" for conditions other than depression)
- Your age
- Your current medications
- Your medical history.
Generally, this antidepressant should be started at a low dose and increased slowly if necessary. For many people with depression, the starting dose is 75 mg total daily (divided into two or three smaller doses). Or instead of several doses a day, the starting dose can be amitriptyline 50 mg to 100 mg once a day at bedtime.
