What is the most important information I should know about cefprozil (Cefzil)?

Do not take this medication if you are allergic to cefprozil, or to similar antibiotics, such as Ceftin, Keflex, Omnicef, and others.

Before taking this medication, tell your doctor or if you are allergic to any drugs (especially penicillins). Also tell your doctor if you have kidney disease or a history of intestinal problems.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Cefprozil will not treat a viral infection such as the common cold or flu.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.

The cefprozil suspension (liquid) may contain phenylalanine. Talk to your doctor before using this form of cefprozil if you have phenylketonuria (PKU).
