What is Zotrim (sulfamethoxazole, trimethoprim, phenazopyridine)?

Zotrim (sulfamethoxazole-trimethoprim tablets and phenazopyridine tablets) is a multi-ingredient prescription medication used to treat urinary tract infections. The package contains 20 tablets (a 10-day supply) of the antibiotic combination sulfamethoxazole-trimethoprim double strength (800 mg. - 160 mg.) which are the active ingredients in Bactrim DS and Septra DS. The package also contains six 200 mg. tablets of the urinary tract pain reliever phenazopyridine. The antibiotic treats urinary tract infections caused by susceptible strains of Enterobacter species, Escherichia coli species, Proteus mirabilis, Morganella morganii and Proteus vulgaris.The phenazopyridine is intended to relieve painful symptoms of a urinary tract infection, but not to treat the underlying infection.

Zotrim for urinary tract infections should not be confused with the OTC weight loss product also called Zotrim.
