Let's take a minute to talk about your medication. 

This is cefoxitin. This antibiotic treats infections caused by germs called 'bacteria'. It cannot treat viral infections, like the common cold. 

Cefoxitin is a type of antibiotic called a 'cephalosporin'. It is similar to penicillin. You should tell your doctor if you are allergic to penicillins, cephalosporins or any antibiotics. Also, talk to your doctor and pharmacist about all of the medicines you take, and about any new medicines you plan to take. 

This medicine is given as an infusion into a vein. It can also be injected into a muscle. You should let your nurse know if you notice any tenderness at the injection site.

People usually tolerate cefoxitin well and start feeling better soon. Common side effects include mild stomach upset, diarrhea or nausea. As with any antibiotic, females should watch for a vaginal yeast infection and obtain treatment if one occurs. 

As with any medicine, rare but more serious side effects could occur. You should tell your doctor right away if you notice any unusual change to your body. This includes a rash, and swelling or tingling in the mouth or throat. Also call your doctor right away if you have diarrhea that is bloody or that lasts for more than 2 days, even if it happens months from now. 

For best results with cefoxitin, finish taking the full course of therapy. Otherwise, the infection could return and become hard to treat.
