Doxepin (doxepin) — Uses, Dosage, Side Effects & Safety

Drug class: Tricyclic Antidepressant (TCA)

Overview

Doxepin is a prescription medication used to treat depression, anxiety, and certain sleep disorders such as insomnia. It is also available as a topical cream for the relief of itching associated with certain skin conditions. Doxepin works by balancing natural chemicals (neurotransmitters) in the brain, particularly serotonin and norepinephrine, which help improve mood, sleep, and anxiety symptoms. As a tricyclic antidepressant, it can also block histamine receptors, which contributes to its sedative and anti-itch effects. Key points for patients: Doxepin may take several weeks to show full benefits. It should be taken exactly as prescribed and not stopped suddenly without consulting your healthcare provider. Always inform your doctor about other medications or supplements you are taking to avoid interactions.
