Elavil is a tricyclic antidepressant with sedative effects. Amitriptyline affects certain chemical messengers (neurotransmitters) that communicate between brain cells and help regulate mood.

Elavil is a prescription medicine used to treat symptoms of depression.

Elavil may also be used for purposes not listed in this medication guide.

You should not use Elavil if you have recently had a heart attack.

Do not use Elavil if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

You may have thoughts about suicide when you first start taking an antidepressant such as amitriptyline, especially if you are younger than 24 years old. Your doctor will need to check you at regular visits for at least the first 12 weeks of treatment.

Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
