Cefprozil, sometimes spelled cefproxil and marketed under the trade name Cefzil, is a second-generation cephalosporin type antibiotic. In Europe it is marketed using the trade names Procef and Cronocef. 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 has shown no increased risk for cross-allergy for cefprozil and several other second-generation or later cephalosporins.
