Indications & Clinical Uses

Zimigut 550 (rifaximin) is commonly used to treat traveler's diarrhea caused by noninvasive strains of Escherichia coli. It is also prescribed for hepatic encephalopathy to reduce the risk of brain function decline. The 550mg strength is specifically formulated for these gastrointestinal conditions. This antibiotic works locally in the gut to target bacteria without significant absorption into the bloodstream.

Side Effects
