Rifamycin : Uses, Side Effects, Interactions & More
Why is this medication prescribed?
Rifamycin is used to treat traveler’s diarrhea caused by certain bacteria. Rifamycin is in a class of drugs called antibiotics. It works by stopping the growth of bacteria that cause diarrhea.
Antibiotics like rifamycin do 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 tablet (it releases the drug in the intestine to allow the drug to work in the intestine where its effects are needed) to be taken by mouth. It is usually taken twice a day (morning and evening) with or without food for 3 days. Take rifamycin at around the same time every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take rifamycin exactly as directed. Do not take more or less or take it more often than prescribed by your doctor.
Take each dose with a glass of liquid (at least 6 to 8 ounces [177 to 240 milliliters] ); do not take it together with alcohol.
Swallow the tablets whole; do not split, chew, or crush them.
You should start to feel better during the first 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 miss doses, your infection may not be fully treated and the bacteria may become resistant to the antibiotics.

Keep this medicine in the container it came in, tightly closed, and out of the reach of children. Store at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medicines out of the sight and reach of children, since many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not child-resistant and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach. http://www.upandaway.org
