WHY is this medicine prescribed?
Rifamycin is used to treat of travelers' diarrhea caused by certain bacteria. Rifamycin is in a class of medications called antibiotics. It works by stopping the growth of the bacteria that cause diarrhea.
Antibiotics such as rifamycin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
HOW should this medicine be used?
Rifamycin comes as a delayed-release (releases the medication in the intestine to allow the medication to work in the intestine where its effects are needed) tablet to take by mouth. It is usually taken twice daily (in morning and evening) with or without food for 3 days. Take rifamycin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take rifamycin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Take each dose with a glass of liquid (at least 6–8 ounces [177–240 milliliters]); do not take it along with alcohol.
Swallow the tablets whole; do not split, chew, or crush them.
You should begin to feel better during the first few days of treatment with rifamycin. If your symptoms do not improve within 48 hours or get worse or if you develop a fever or bloody diarrhea, call your doctor right away.
Take rifamycin until you finish the prescription, even if you feel better. If you stop taking rifamycin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
