Doxepin is a medication belonging to the tricyclic antidepressant (TCA)[10] class of drugs used to treat major depressive disorder, anxiety disorders, chronic hives, and insomnia.[10][11] For hives it is a less preferred alternative to antihistamines.[10] It has a mild to moderate benefit for sleeping problems.[12] It is used as a cream for itchiness due to atopic dermatitis or lichen simplex chronicus.[13]

Common side effects include sleepiness, dry mouth, constipation, nausea, and blurry vision.[10] Serious side effects may include increased risk of suicide in those under the age of 25, mania, and urinary retention.[10] A withdrawal syndrome may occur if the dose is rapidly decreased.[10] Use during pregnancy and breastfeeding is not generally recommended.[14][15] Although how it works for treating depression remains an area of active inquiry, it may involve increasing the levels of norepinephrine, along with blocking histamine, acetylcholine, and serotonin.[10]

Doxepin was approved for medical use in the United States in 1969.[10] It is available as a generic medication.[14][16][17] In 2020, it was the 252nd most commonly prescribed medication in the United States, with more than 1 million prescriptions.[18][19]
