What is the most important information I should know about cefoxitin (Mefoxin)?

Do not use this medication if you are allergic to cefoxitin, or to similar antibiotics, such as Ceftin, Cefzil, Keflex, Omnicef, and others.

Before using this medication, tell your doctor if you are allergic to any drugs (especially penicillin). Also tell your doctor if you have liver or kidney disease, diabetes, heart failure, cancer, a stomach or intestinal disorder, or if you are malnourished.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Cefoxitin will not treat a viral infection such as the common cold or flu.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.

This medication can cause you to have unusual results with certain lab tests, including tests to check for glucose (sugar) in the urine. Tell any doctor who treats you that you are using cefoxitin.
