Cefprozil (Cefzil) is an antibiotic in the Cephalosporin Family. Cefprozil is used to treat bronchitis, ear infections and skin infections.

Cefprozil is rarely used as an acne treatment. Laboratory antibiotic susceptibility testing does indicate that the acne causing P. acnes bacteria tends to be sensitive to Cephalosporin family antibiotics, including Cefprozil. There is little clinical research about the utility of Cefprozil for the treatment of acne.
