Take this medication by mouth with or without food as directed by your doctor, usually once a day or twice a day (every 12 hours).

The dosage is based on your medical condition and response to treatment.

For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

Continue to use this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.

Some medications can bind with cefdinir preventing its full absorption. If you take antacids containing magnesium or aluminum, iron supplements, or vitamin/mineral products, take them at least 2 hours apart from cefdinir.

Tell your doctor if your condition lasts or gets worse.
