Rifaximin 200 mg is an antibiotic used to treat traveler’s diarrhea caused by specific bacteria, mainly non-invasive strains of Escherichia coli (E. coli). It is helpful for both adults and children aged 12 and up. This medicine works by inhibiting the growth of germs that cause diarrhea, thereby relieving symptoms within 24 to 48 hours of commencing treatment. Rifaximin is typically administered as a pill three times each day for three days. In addition to treating traveler’s diarrhea, rifaximin is used to avoid bouts of hepatic encephalopathy, which can occur in persons with liver disease, and to treat irritable bowel syndrome (IBS-D). It is critical to take rifaximin exactly as advised by your doctor, as discontinuing the medicine too soon can result in incomplete therapy and increase the risk of antibiotic resistance. Rifaximin is generally well-tolerated and has few adverse effects, making it an excellent choice for treating gastrointestinal disorders caused by bacterial infections. Always see a doctor if your symptoms do not improve or worsen after starting the medicine.
