Cefdinir is used to treat a wide variety of bacterial infections. This medication is known as a cephalosporin antibiotic. It works by stopping the growth of bacteria.This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.
How to use Cefdinir
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). Shake the bottle well before each dose.
The dosage is based on your medical condition and response to treatment. In children, the dose is also based on weight.
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 allow bacteria to continue to grow, which may result in a relapse 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.
