Rifaxiheal 400 mg contains Rifaximin 400 mg, an antibiotic that works locally in the intestines with very minimal absorption into the bloodstream.
Common Uses
Doctors may prescribe Rifaxiheal 400 mg for conditions such as:
- IBS-D (Irritable Bowel Syndrome with diarrhea)
- Traveler’s diarrhea (caused by E. coli)
- Hepatic encephalopathy prevention (reduces ammonia-producing gut bacteria)
- Certain cases of infectious diarrhea
How It Works
- Rifaximin stays mostly inside the gut and helps:
- Reduce harmful bacteria
- Reduce inflammation
- Improve stool consistency and decrease diarrhea
Usual Dosage (doctor-determined)
- Dosage depends on the condition:
- Traveler’s diarrhea: often short course
- IBS-D: usually a fixed multi-day regimen
- Hepatic encephalopathy: long-term maintenance
- Never self-prescribe. Rifaximin must be taken exactly as advised by a healthcare professional.
Possible Side Effects
Most are mild:
- Nausea
- Headache
- Bloating or gas
- Abdominal pain
- Fatigue
Rare:
- Severe allergic reaction
- Persistent diarrhea (C. difficile risk)
- Important Precautions
- Tell your doctor if you have liver disease.
- Not effective for diarrhea with fever or blood in stool.
- Avoid if allergic to rifamycin antibiotics.
Drug Interactions
Usually minimal because absorption is low, but still inform your doctor about:
- Other antibiotics
