Two medicines, side by side

Cefprozil vs cefdinir

Cefprozil and cefdinir are both labeled for bacterial infections. Drugs@FDA records approvals of cefprozil since 1991 and of cefdinir since 1997. Pharmacies paid $0.925 per cefprozil 500 mg tablet and $0.458 per cefdinir 300 mg capsule (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like.

Check it at the source: the cefprozil FDA label on DailyMed (effective May 5, 2024); the cefdinir FDA label on DailyMed (effective October 14, 2025).
