Omnicef is in a group of drugs called cephalosporin antibiotics. It works by fighting bacteria in your body.

Omnicef is used to treat many different types of infections caused by bacteria, such as acute flare-ups of chronic bronchitis, middle ear infections, throat and tonsil infections, pneumonia, sinus infections and skin infections.

Do not take Omnicef 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. Omnicef will not treat a viral infection such as the common cold or flu.
