What is the most important information I should know about cefdinir (Omnicef)?

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

Before taking this medication, tell your doctor if you are allergic to any drugs (especially penicillin). 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. Cefdinir 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.
