Rifaximin

Rifaximin is an antibiotic commonly prescribed for treating bacterial infections in the intestines. It is particularly effective against traveler’s diarrhea, irritable bowel syndrome (IBS) with diarrhea, and hepatic encephalopathy. Known for its targeted action in the digestive tract, Rifaximin works without significantly affecting the body's normal bacteria, making it a preferred choice for specific intestinal infections.

Uses of Rifaximin

• Treatment of traveler’s diarrhea caused by E. coli
• Management of irritable bowel syndrome (IBS) with diarrhea
• Prevention and treatment of hepatic encephalopathy

How Rifaximin Works

Rifaximin works by inhibiting the growth of bacteria in the intestines. It binds to bacterial RNA polymerase, preventing the bacteria from synthesizing essential proteins. This localized action ensures effective treatment of intestinal infections while minimizing systemic side effects.
