Two medicines, side by side

Doxepin vs duloxetine

Doxepin and duloxetine are both labeled for depression and anxiety. Drugs@FDA records approvals of doxepin since 1969 and of duloxetine since 2004. Pharmacies paid $0.0779 per doxepin 10 mg capsule and $0.102 per duloxetine HCl DR 30 mg capsule (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, doxepin is a tricyclic antidepressant and duloxetine a serotonin and norepinephrine reuptake inhibitor.

Check it at the source: the doxepin FDA label on DailyMed (effective December 30, 2025); the duloxetine FDA label on DailyMed (effective May 14, 2024).
