What should I avoid while taking cefdinir (Omnicef, Omnicef Omni-Pac)?

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop taking cefdinir and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

Avoid using antacids or mineral supplements that contain iron within 2 hours before or after taking cefdinir. Antacids or iron can make it harder for your body to absorb cefdinir. This does not include baby formula fortified with iron.

Taking cefdinir with products that contain iron may cause your stools (bowel movements) to appear red in color. If this discoloration looks like blood in your stools, call your doctor.

What other drugs will affect cefdinir (Omnicef, Omnicef Omni-Pac)?

Tell your doctor about all other medications you use, especially:

• probenecid (Benemid); or
• vitamin or mineral supplements that contain iron.

This list is not complete and other drugs may interact with cefdinir. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.

Where can I get more information?

Your pharmacist can provide more information about cefdinir.

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
