Cefaclor

Pronunciation

Generic Name: cefaclor (SEFF-uh-klor)
Brand Name: Raniclor

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.
