What is cefixime?

Cefixime is an antibiotic that may be used to treat many different types of infections caused by bacteria.

Cefixime stops bacteria from forming a cell wall, which bacteria need to survive. This decreases the number of bacteria in your body, which helps your body fight the infection.

Cefixime was FDA approved in 1989.


You should not take cefixime if you are allergic to cefixime, or to similar  antibiotics , such as  Ceftin ,  Cefzil ,  Keflex ,  Omnicef , and others. Tell your doctor if you are allergic to  penicillins .
