Information on Tablets A-Z
Generic name: Cefdinir
Why is this drug prescribed: Omnicef is a member of the family of antibiotics known as cephalosporins. It is used to treat mild to moderate infections, including: Acute flare-ups of chronic bronchitis Middle ear infections (otitis media) Throat and tonsil infections (pharyngitis/tonsillitis) Pneumonia Sinus infections Skin infections
Most important fact about this drug: Omnicef, like other antibiotics, works best when there is a constant amount in the blood. To maintain effective blood levels, be sure to take every dose on schedule.
How should you take this medication: Omnicef is available in capsules (for individuals aged 13 years and up) and an oral suspension (for children aged 6 months to 12 years). Shake the oral suspension thoroughly before each use. The drug can be taken with or without food. Be sure to finish your entire prescription, even if you begin to feel better. If you stop taking the drug too soon, some germs may survive and cause a relapse. If you use antacids, iron supplements, or multivitamins containing iron, allow at least 2 hours between a dose of these products and a dose of Omnicef. Antacids and iron tend to reduce the amount of Omnicef in the bloodstream. It's okay, however, to combine iron-fortified infant formula with Omnicef suspension. --If you miss a dose... Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at once. --Storage instructions... Both the capsules and the oral suspension can be stored at room temperature. The suspension will keep for 10 days, after which any unused portion must be thrown away.

If you develop symptoms such as diarrhea while taking this medication, notify your doctor.

If you have a seizure while using Omnicef, stop taking it and call your doctor immediately. Omnicef suspension contains 2.86 grams of sugar per teaspoonful.
