Doxepin is used for:

Treating depression or anxiety in certain patients. It may also be used for other conditions like gastrointestinal ulceration and other GI-problems (e.g. irritable bowel syndrome), whether part of depression or not.

Doxepin is a tricyclic antidepressant. It is not known exactly how it works. It may increase the activity of certain chemicals in the brain, which help elevate mood.

• you have certain prostate problems (eg, asymptomatic prostatic hypertrophy), glaucoma, or trouble urinating
• you are taking cisapride, clonidine, dofetilide, H₁ antagonists (eg, astemizole, terfenadine), or ibutilide, or you have taken a monoamine oxidase (MAO) inhibitor (eg, furazolidone, phenelzine, isocarboxazid) within the past 14 days

Contact your doctor or health care provider right away if any of these apply to you.
