Generic name: CeftibutenBrand names: Cedax

Why is Cedax prescribed?

Cedax cures mild-to-moderate bacterial infections of the throat, ear, and respiratory tract. Among these infections are strep throat, tonsillitis, and acute otitis media (middle ear infection) in children and adults. Cedax is also prescribed for acute flare-ups of chronic bronchitis in adults. Cedax is a cephalosporin antibiotic.

Most important fact about Cedax

If you are allergic to either penicillin or cephalosporin antibiotics in any form, double-check with your doctor before taking Cedax. There is a possibility that you are allergic to both types of medication and if a reaction occurs, it could be extremely severe. (Symptoms include swelling of the face, lips, tongue, and throat, making it difficult to breathe.) If you take the drug and feel any signs of this reaction, seek medical attention immediately.

How should you take Cedax?

To make certain your infection is fully cleared up, take all the Cedax your doctor prescribes, even if you begin to feel better after the first few days.

If you are using the oral suspension, it must be taken at least 2 hours before a meal or 1 hour after. Shake well before using.

  • 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. Never take 2 doses at the same time.
  • Storage instructions...Keep the oral suspension in the refrigerator, and discard any unused portion after 14 days. Capsules may be stored at room temperature.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, notify your doctor as soon as possible. Only your doctor can determine whether it is safe for you to continue taking Cedax.

  • Side effects in adults may include:Diarrhea, headache, nausea
  • The most common side effect in children is:Diarrhea (especially in children age 2 and under)

Why should Cedax not be prescribed?

If you are sensitive to or have ever had an allergic reaction to Cedax, or other cephalosporins, such as cephalexin hydrochloride, do not take Cedax.

Make sure your doctor is aware of any drug reactions you have experienced. If you've ever had a reaction to penicillin, you're more likely to react to Cedax. If a reaction occurs, you'll have to stop taking Cedax.

Special warnings about Cedax

If you have a history of gastrointestinal disease, particularly colitis, take Cedax with caution. If you develop diarrhea while taking Cedax, check with your doctor. The problem could be a sign of a serious condition.

Tell your doctor if you have kidney problems. Your dosage may have to be lowered. If you are diabetic, be sure to tell your doctor before starting therapy with Cedax; the oral suspension contains sugar.

If new infections (called superinfections) occur, talk to your doctor. You may need to be treated with a different antibiotic.

Do not give Cedax to other people or use it for other infections before checking with your doctor. The drug is not effective against every type of germ.

Possible food and drug interactions when taking Cedax

Ranitidine hydrochloride may boost the level of Cedax in your system. Check with your doctor before combining these drugs.

Special information if you are pregnant or breastfeeding

The effects of Cedax during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, tell your doctor immediately. Cedax may appear in breast milk and could affect a nursing infant. If Cedax is essential to your health, your doctor may advise you to stop breastfeeding until your treatment is finished.
