These factors may affect how you should use this medication.
Allergy: Before starting treatment with cefprozil, inform your doctor about any adverse reactions you have had to medications, especially cefprozil, cephalosporins, and penicillins. Some people allergic to penicillin may also be allergic to cephalosporins such as cefprozil. If you have an allergic reaction, contact a doctor.
