What is cefaclor?

Cefoxitin is a cephalosporin (SEF a low spor in) antibiotic. It works by fighting bacteria in your body.

Cefaclor is used to treat many kinds of bacterial infections, such as bladder infection, ear infection, skin infection, or infection of the respiratory tract.

Cefaclor may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking cefaclor?

Do not take this medication if you are allergic to cefaclor or to other cephalosporin antibiotics, such as:

  • cefadroxil (Duricef);
  • cefazolin (Ancef);
  • cefdinir (Omnicef);
  • cefditoren (Spectracef);

How should I take cefaclor?

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Cefaclor works best if you take it with a meal or within 30 minutes of a meal.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Do not crush, chew, or break an extended-release tablet. Swallow it whole.

This medicine can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using cefaclor.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Cefaclor will not treat a viral infection such as the flu or a common cold.

Store the tablets and capsules at room temperature away from moisture and heat.

Store the liquid medicine in the refrigerator, do not freeze. Throw away any unused liquid after 14 days.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include nausea, vomiting, stomach pain, and diarrhea.

What should I avoid while taking cefaclor?

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

What are the possible side effects of cefaclor?

Get emergency medical help if you have signs of an allergic reaction: hives, numbness or tingling; weakness, feeling light-headed; difficult breathing; swelling of your face, lips, tongue, or throat.
