Claforan is used for treating infections caused by certain bacteria. It is also used to prevent bacterial infections before, during, or after certain surgeries.
Claforan is a cephalosporin antibiotic. It works by weakening and rupturing the cell wall, killing the bacteria.
Do NOT use Claforan if:
- you are allergic to any ingredient in Claforan or to any other cephalosporin antibiotic (eg, cephalexin)
Contact your doctor or health care provider right away if any of these apply to you.

Do not treat diarrhea without first checking with your doctor.
