How Long Do Cefdinir Side Effects Last?

Cefdinir is an antibiotic used to treat certain infections caused by bacteria, such as pneumonia, bronchitis, ear infections, sinusitis, pharyngitis, tonsillitis, and skin infections.

Antibiotics will not work for colds, flu, or other viral infections. This medication is sometimes prescribed for other purposes; ask your doctor or pharmacist for more information.

Precautionary measures

Before taking Cefdinir, tell your doctor and pharmacist if you are allergic to Cefdinir or any other cephalosporin antibiotic, such as Ceclor or Cefalexin (Keflex), penicillin, or any other drugs.

Tell your doctor and pharmacist that prescription and non-prescription medicines you are taking, especially probenecid (Benemid, Probalan) and vitamins.

Be aware that antacids containing magnesium or aluminum and products containing iron interfere with Cefdinir, which makes it less effective.

Take Cefdinir 2 hours before or 2 hours after antacids or iron products. Tell your doctor if you have or have ever had colitis, diabetes, or kidney disease.


In case of overdose, call the local poison control center-1222. If the victim collapses or is not breathing, call the local emergency services for 911.
