Cautions & Contraindications

Warnings & Precautions

Rifaxin has not been shown to be effective in patients whose diarrhea is accompanied by fever and/or blood in the stool. Treatment with Rifaxin should be stopped if diarrhea symptoms worsen or continue beyond 24 to 48 hours, and switching to an alternative antibiotic should be considered. Pseudomembranous colitis has been reported with almost all antibacterial agents and can range in severity from mild to life-threatening. For this reason, the possibility of this condition should be kept in mind in any patient who develops diarrhea after taking an antibacterial agent.

Contraindications

Contraindicated in anyone known to be hypersensitive to Rifaximin, to other rifamycin antimicrobials, or to any other ingredient in this product.
