WHY is this medicine prescribed?
Cefdinir is an antibiotic used to treat certain infections caused by bacteria, such as pneumonia, bronchitis, ear infection, sinusitis, pharyngitis, tonsillitis, and skin infections. Antibiotics will not work for colds, flu, or other viral infections.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
HOW should this medicine be used?
Cefdinir comes as a capsule and as an oral suspension. It is usually taken once or twice a day. Shake the suspension well before each use to mix the medication evenly. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cefdinir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take cefdinir even if you feel well. Do not stop taking cefdinir without talking to your doctor.
What SPECIAL PRECAUTIONS should I follow?
Before taking cefdinir,
- tell your doctor and pharmacist if you are allergic to cefdinir or any other cephalosporin antibiotic such as cefaclor (Ceclor) or cephalexin (Keflex), penicillin, or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially probenecid (Benemid, Probalan) and vitamins.
- be aware that antacids containing magnesium or aluminum and products containing iron interfere with cefdinir, making 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.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking cefdinir, call your doctor.
What SPECIAL DIETARY instructions should I follow?
Cefdinir may cause an upset stomach. Take cefdinir with food or milk.
What should I do IF I FORGET to take a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What SIDE EFFECTS can this medicine cause?
Cefdinir may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- upset stomach
- loss of appetite
If you experience any of the following symptoms, call your doctor immediately:
- swelling of the face, eyes, lips, tongue, arms, or legs
- difficulty breathing or swallowing
- vaginal infection
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at
] or by phone [1-800-332-1088].
What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
What should I do in case of OVERDOSE?
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
What OTHER INFORMATION should I know?
Keep all appointments with your doctor and laboratory. Your doctor may order certain lab tests to check your response to cefdinir.
If you are diabetic, use Clinistix or TesTape (but not Clinitest) to test your urine for sugar while taking this drug; cefdinir may cause false positive results.
Do not let anyone else take your medication. Your prescription is probably not refillable. If you still have symptoms of infection after you finish the cefdinir, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
