Fosfomycin is an antibiotic used to treat or prevent urine infections (also called urinary tract infections or UTIs) caused by the E.coli bacteria. It works by killing or stopping the growth of bacteria and getting rid of the infection.

This medicine is usually used for people who are unable take other antibiotics for UTIs or if other antibiotics don't work as well.
