Rifaximin Online is a medicine that is normally administered for a brief period of treatment, ranging from 3 to 14 days depending on the illness being treated. Here are some important details regarding how long rifaximin lasts.
For travelers' diarrhea, 200 mg of rifaximin is used three times a day for three days.
To lower the incidence of recurrence in hepatic encephalopathy, rifaximin 550 mg is used twice daily for up to 6 months. In one trial, the rifaximin group received therapy for an average of 130 days.
For irritable bowel syndrome with diarrhea (IBS-D), rifaximin 550 mg is given three times daily for two weeks. More rifaximin patients reported adequate alleviation of global IBS symptoms than placebo patients across a 12-week period (2 weeks of therapy + 10 weeks of follow-up).
Rifaximin is poorly absorbed systemically, having a half-life of around 6 hours in IBS-D patients. It is mostly removed unaltered in feces, with very little excreted in pee.
To summarize, while the effects of rifaximin might continue for weeks after finishing a course, the medicine itself is eliminated from the body rather fast due to limited absorption and rapid excretion. Patients should take the medication exactly as advised by their doctor.
