Indications & Clinical Uses

Rifaximin 400mg tablets are commonly used to address symptoms of traveler's diarrhea caused by noninvasive strains of E. coli. They are also prescribed for irritable bowel syndrome with diarrhea to help manage frequent loose stools. This medication targets bacteria in the gut without significant absorption into the bloodstream.

Side Effects

Rifaximin 400mg works by reducing the growth of certain bacteria in the intestines, which can help improve symptoms like diarrhea and stomach discomfort. Many users notice a reduction in loose stools and abdominal pain within a few days of starting treatment.

Precautions & Warnings

Store rifaximin 400mg tablets at room temperature away from moisture and heat. Keep the medication in its original packaging until ready to use. If you experience severe diarrhea or symptoms worsen after starting treatment, consult a healthcare provider promptly.

Avoid Interactions

Rifaximin has minimal systemic absorption, so interactions with other medications are generally rare. However, it is important to inform your doctor about all prescription and over-the-counter drugs you are taking. Avoid alcohol while using rifaximin to prevent potential digestive discomfort.
