Rifaximin: What It Is and When You Might Need It

Rifaximin is a gut‑focused antibiotic that stays mostly in the intestines. Because it isn’t absorbed much into the bloodstream, it can fight bacterial overgrowth without many systemic effects. Doctors usually turn to it for three main reasons: treating traveler’s diarrhea, easing symptoms of IBS‑D (irritable bowel syndrome with diarrhea), and reducing complications in hepatic encephalopathy.

If you’ve ever had a bout of diarrhea after a trip abroad, you might have heard Rifaximin mentioned as a short‑term cure. It’s also become a popular option for people with IBS‑D who haven’t found relief from diet changes alone. In liver disease, the drug helps lower ammonia‑producing bacteria, which can improve mental clarity.

How Rifaximin Works

The medication targets bacterial DNA replication, stopping the microbes from multiplying. Since it stays in the gut, it attacks the bad bacteria where they live while leaving most of the rest of your body untouched. This local action means fewer typical antibiotic side effects like rash or joint pain, but it still can cause some gut‑related issues.

Because it’s not widely absorbed, Rifaximin doesn’t usually interact with other medicines that are processed in the liver. However, it’s wise to avoid taking it with other gut antibiotics at the same time, as that could diminish its effectiveness.

What to Know Before You Take It

Typical doses: For traveler’s diarrhea, adults often take 200 mg three times a day for three days. For IBS‑D, the standard course is 550 mg twice daily for 14 days, and it may be repeated after a month if symptoms return. For hepatic encephalopathy, doctors usually prescribe 550 mg twice daily for up to 12 months, depending on response.

Common side effects include mild nausea, bloating, or a brief increase in stomach cramps. These usually settle once the body adjusts. If you notice persistent headache, fever, or a rash, stop the medication and contact a health professional.

Who should avoid it? People with known hypersensitivity to Rifaximin or other rifamycin antibiotics should stay away. Pregnant or breastfeeding women should only use it if a doctor says the benefits outweigh any potential risk.
