Description

Gifaxin 200 Tablet contains Rifaximin, a broad-spectrum, gut-specific antibiotic mainly used for treating intestinal infections. Unlike most antibiotics, Rifaximin works locally in the intestine because it is minimally absorbed into the bloodstream. This makes it particularly useful in conditions related to bacterial overgrowth in the gut.

Uses / Indications

Traveler’s diarrhea caused by non-invasive Escherichia coli
Irritable Bowel Syndrome with Diarrhea (IBS-D)
Hepatic encephalopathy (prevents recurrence by lowering gut ammonia-producing bacteria)
Small intestinal bacterial overgrowth (SIBO)
Other intestinal infections as advised by the doctor

How It Works (Mechanism of Action)

Rifaximin (200 mg): Belongs to the rifamycin class of antibiotics.
Blocks bacterial RNA synthesis → stops bacterial growth and multiplication.
Works locally in the gut, targeting harmful bacteria while sparing beneficial ones to some extent.
