Two medicines, side by side

Azelaic acid vs clindamycin

Azelaic acid and clindamycin are both labeled for acne. Drugs@FDA records approvals of azelaic acid since 1995 and of clindamycin since 1970. Pharmacies paid $0.441 per gram (Azelaic acid 15% gel) and $0.137 per gram (Clindamycin ph 1% gel) (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Only the clindamycin label carries a boxed warning.

Check it at the source: the azelaic acid FDA label on DailyMed (effective November 11, 2021); the clindamycin FDA label on DailyMed (effective March 10, 2026).
