Two medicines, side by side

Amoxicillin vs cefdinir

Amoxicillin and cefdinir are both labeled for bacterial infections. Drugs@FDA records approvals of amoxicillin since 1974 and of cefdinir since 1997. Pharmacies paid $0.0788 per amoxicillin 500 mg capsule and $0.458 per cefdinir 300 mg capsule (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, amoxicillin is a penicillin-class antibacterial and cefdinir a cephalosporin antibacterial.
