Rifaximin Tablets 400 mg Uses
Rifaximin is an antibiotic used primarily to treat traveler's diarrhea caused by non-invasive strains of Escherichia coli. It is also used in the management of irritable bowel syndrome with diarrhea (IBS-D) and to reduce the risk of hepatic encephalopathy recurrence in adults with liver disease. This medication works in the gut and is not significantly absorbed into the bloodstream.
How Rifaximin Works
Rifaximin is a rifamycin derivative that inhibits bacterial RNA synthesis by binding to the beta-subunit of bacterial DNA-dependent RNA polymerase. It has a broad spectrum of activity against both gram-positive and gram-negative bacteria, but its poor oral absorption (less than 0.4%) allows it to act locally in the gastrointestinal tract. This makes it effective for gut-specific infections without systemic side effects.
Common Side Effects of Rifaximin
Most side effects are mild and may include:
- Nausea
- Headache
- Abdominal pain or bloating
- Flatulence
- Constipation or diarrhea
- Dizziness
Serious side effects are rare but may include allergic reactions, Clostridioides difficile-associated diarrhea, or worsening of hepatic encephalopathy symptoms. Seek medical attention if you experience severe abdominal pain, bloody stools, or signs of an allergic reaction.
