Ceftanir is used for treating mild to moderate infections caused by certain bacteria. Ceftanir is a cephalosporin antibiotic. It works by killing sensitive bacteria.
Use Ceftanir as directed by your doctor.
- Ceftanir may be taken with or without food. If stomach upset occurs, take it with food to reduce stomach irritation.
- Do not take an antacid that has magnesium or aluminum in it within 2 hours before or after you take Ceftanir.
- Do not take a product that has iron in it within 2 hours before or after you take Ceftanir. However, you may give Ceftanir along with iron-fortified infant formula.
- Ceftanir works best if taken at the same times each day.
- To clear up your infection completely, take Ceftanir for the full course of treatment. Keep taking it even if you feel better in a few days.
- If you miss a dose of Ceftanir, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Ceftanir.
Store Ceftanir at 77 degrees F (25 degrees C). Brief storage at temperatures between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Ceftanir out of the reach of children and away from pets.

Important Ceftanir Safety Information
- Ceftanir may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Ceftanir with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
- Ceftanir only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use Ceftanir for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Long-term or repeated use of Ceftanir may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- If you are taking Ceftanir and a product that contains iron, your stools may turn a reddish color. This is normal and not a cause for concern.
- Diabetes patients - Ceftanir may cause the results of some tests for urine ketones or glucose to be wrong. Ask your doctor before you change your diet or the dose of your diabetes medicine.
- Ceftanir may interfere with certain lab tests (eg, Coomb tests). Be sure your doctor and lab personnel know you are using Ceftanir.
