Cefprozil, sometimes spelled cefproxil and sold under the brand name Cefzil, is a cephalosporin type antibiotic. In Europe, it is sold by the name Procef. It can be used to treat bronchitis, ear infections, skin infections, and other bacterial infections. It comes as a tablet and as a liquid suspension.

Although there is a widely quoted cross-allergy risk of 10% between cephalosporins and penicillin, an article in the Journal of Family Practice (February 2006)[1] has shown no increased risk for cross-allergy for cefprozil and several other 2nd generation or later cephalosporins.
