Doxepin for Sleep: A Complete Guide to Managing Insomnia

Struggling to stay asleep through the night can significantly affect your health and daily functioning. Doxepin, a prescription medication, is an effective option for adults experiencing sleep maintenance insomnia, helping you stay asleep without causing next-day grogginess.

What Is Doxepin?

Doxepin is a tricyclic antidepressant (TCA) originally developed for depression and anxiety. In low doses (1–6 mg), it is FDA-approved under the brand name Silenor for insomnia treatment. At these low doses, it works differently than for depression, targeting histamine receptors in the brain to promote uninterrupted sleep.
