ANTIBIOTIC

Uses of Rifaximin

  • Rifaximin is used to treat traveler's diarrhea caused by E. coli bacteria. It also helps prevent a condition called hepatic encephalopathy, which happens when the liver isn’t working well. This condition can lead to confusion, restlessness, and muscle issues. 
  • Rifaximin helps stop these symptoms from returning. It can be taken alone or with other medicines like lactulose to manage the condition.

Side effects of Rifaximin

  • Feeling or being sick
  • Stomach ache or bloating/swelling
  • Diarrhoea
  • Depressed mood
  • Dizziness
  • Headache
  • Shortness of breath
  • Accumulation of fluid in the abdomen
  • Rash or itching
  • Muscle cramps
  • Joint pain
  • Swelling of ankles, feet or fingers

How Rifaximin works

  • Rifaximin, a semi-synthetic derivative of rifampin, functions by binding to the beta-subunit of bacterial RNA polymerase. This binding action disrupts a step in transcription, leading to the stoppage of bacterial protein synthesis and, consequently, impeding bacterial growth.
