Two medicines, side by side

Oxazepam vs alprazolam

Oxazepam and alprazolam are both labeled for anxiety. Drugs@FDA records approvals of oxazepam since 1965 and of alprazolam since 1981. Pharmacies paid $0.725 per oxazepam 10 mg capsule and $0.0236 per alprazolam 0.25 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like.

Check it at the source: the oxazepam FDA label on DailyMed (effective July 11, 2025); the alprazolam FDA label on DailyMed (effective January 18, 2023).
