Two medicines, side by side

Lorazepam vs midazolam

Lorazepam is labeled for anxiety; midazolam has no indication this site maps. Their labels share no use, so they are not alternatives to each other. Drugs@FDA records approvals of lorazepam since 1977 and of midazolam since 1985. Pharmacies paid $0.0344 per lorazepam 0.5 mg tablet and $0.233 per mL (Midazolam HCl 2 mg/2 mL vial) (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Midazolam's other strengths are brand-only: $327.05 per unit (Nayzilam 5 mg nasal spray).

Check it at the source: the lorazepam FDA label on DailyMed (effective July 9, 2025); the midazolam FDA label on DailyMed (effective January 1, 2024).
