Cefaclor is used for:
Treating infections caused by certain bacteria.
Cefaclor is a cephalosporin antibiotic. It kills sensitive bacteria by interfering with formation of the bacteria’s cell wall while it is growing. This weakens the cell wall and it ruptures, resulting in the death of the bacteria.
Do NOT use cefaclor if:
- you are allergic to any ingredient in cefaclor or any other cephalosporin antibiotic (eg, cephalexin)
Contact your doctor or health care provider right away if any of these apply to you
Before using cefaclor:
Some medical conditions may interact with cefaclor. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have diarrhea, a stomach infection, or a blood clotting disorder
- if you have phenylketonuria
- if you have had a severe allergic reaction (eg, a severe rash, hives, breathing difficulties, dizziness) to a penicillin antibiotic (eg, amoxicillin) or other beta-lactam antibiotic (eg, imipenem)
Some MEDICINES MAY INTERACT with cefaclor. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Probenecid because it may increase the actions and side effects of cefaclor
- Oral anticoagulants (eg, warfarin) because side effects, including risk of bleeding, may be increased by cefaclor
This may not be a complete list of all interactions that may occur. Ask your health care provider if cefaclor may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
