Cephalosporins (Systemic)

Cephalosporins | Before Using | Proper Use | Precautions | Side Effects | Additional Information

Proper Use of This Medicine

Cephalosporins may be taken on a full or empty stomach. If this medicine upsets your stomach, it may help to take it with food.

Cefaclor extended-release tablets, cefditoren, cefpodoxime, and cefuroxime axetil should be taken with food to increase absorption of the medicine. Ceftibuten oral suspension should be taken on an empty stomach, at least 2 hours before or 1 hour after a meal.

For patients taking the oral liquid form of this medicine:

  • This medicine is to be taken by mouth. Use a specially marked measuring spoon or other device to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid.
  • Do not use after the expiration date on the label since the medicine may not work properly after that date. Check with your pharmacist if you have any questions about this.

To help clear up your infection completely, keep taking this medicine for the full time of treatment , even if you begin to feel better after a few days. If you have a “strep” infection, you should keep taking this medicine for at least 10 days. This is especially important in “strep” infections since serious heart or kidney problems could develop later if your infection is not cleared up completely. Also, if you stop taking this medicine too soon, your symptoms may return.

This medicine works best when there is a constant amount in the blood or urine. To help keep the amount constant, do not miss any doses. Also, it is best to take the doses at evenly spaced times, day and night . For example, if you are to take four doses a day, the doses should be spaced about 6 hours apart. If this interferes with your sleep or other daily activities, or if you need help in planning the best times to take your medicine, check with your health care professional.

Dosing - The dose of these medicines will be different for different patients. Follow your doctor's orders or the directions on the label . The following information includes only the average doses of these medicines. Your dose may be different if you have kidney disease. If your dose is different, do not change it unless your doctor tells you to do so.

The number of capsules or tablets or teaspoonfuls of suspension that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are taking a cephalosporin .
