Adapin is in a group of drugs called tricyclic antidepressants. Adapin affects chemicals in the brain that may become unbalanced.
Adapin is used to treat symptoms of depression and/or anxiety associated with alcoholism, psychiatric conditions, or manic-depressive conditions.
Adapin may also be used for other purposes not listed in this medication guide.
Most important: Do not use this medication if you are allergic to doxepin, or if you have glaucoma or problems with urination. Do not use doxepin if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Serious, life-threatening side effects can occur if you take doxepin before the MAO inhibitor has cleared from your body.
You may have thoughts about suicide when you first start taking an antidepressant, 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.
Call your doctor at once if you have any new or worsening symptoms 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.
