RIFAXIMIN

Overview:

Rifaximin is an antibiotic, but it works a bit differently from the typical ones you might take for a sore throat or chest infection. It mainly stays in your gut and doesn’t spread much through your bloodstream. It’s used to treat certain stomach and bowel-related conditions, especially those linked to bacteria. Because it stays in the intestines, it works right where it’s needed with fewer effects on the rest of the body.
Classification:
Antibiotic
Uses:
Doctors may prescribe rifaximin to treat:
Traveler’s diarrhea caused by certain bacteria

Irritable bowel syndrome with diarrhea (IBS-D)

Hepatic encephalopathy, a condition in people with liver disease that can lead to confusion, by reducing toxin-producing gut bacteria

Sometimes used off-label for small intestinal bacterial overgrowth (SIBO)

How It Work:
Rifaximin targets and kills certain bacteria in your gut. Because it doesn’t get absorbed much into your blood, it works mainly inside the intestines, helping to reduce harmful bacteria without disturbing the whole body. This makes it especially useful for gut-related problems, and it tends to cause fewer side effects than many other antibiotics.

Dosage:
As prescribed by your doctor.

Precautions:
Allergies: If you’re allergic to rifampin or similar antibiotics, let your doctor know.

Liver disease: If you’re taking it for hepatic encephalopathy, your doctor may monitor you more closely.

Pregnancy and breastfeeding: Talk to your doctor — it’s generally considered safe in some cases, but always check.

Antibiotic resistance: Since rifaximin is an antibiotic, it should only be used as prescribed to help prevent resistance. Don’t use it unnecessarily or share it with others.
