Description

Indications

Rifaximin is indicated for the treatment of traveler’s diarrhea, which is caused by the common bacterium Escherichia coli. It is also prescribed for managing diarrhea associated with irritable bowel syndrome and can aid in preventing hepatic encephalopathy, a brain disorder associated with liver disease. Rifaximin should not be used in cases where the patient is experiencing a fever or bloody diarrhea.

This medication functions by inhibiting bacterial growth and is solely effective against bacterial infections. It is not useful in treating viral infections, such as the flu or the common cold. Overuse of antibiotics can result in their decreased efficacy for future infections, hence, Rifaximin should only be used when necessary.

Uses and Dosage

Rifaximin is available in tablet form and can be taken orally with or without food. The dosage and frequency of rifaximin intake depend on the condition being treated.

For traveler’s diarrhea, the usual regimen is three times daily for three days. For prevention of episodes of hepatic encephalopathy, the usual dosage is twice daily, whereas for treating irritable bowel syndrome, the medication is taken three times daily for 14 days.

Consistent timing of rifaximin intake is essential to avoid missing doses. The medication must be taken precisely as directed, without taking more or less than recommended, or increasing the frequency of administration.

Patients taking rifaximin for traveler’s diarrhea should experience symptomatic improvement within 24 to 48 hours of starting treatment. In cases where symptoms persist, worsen, or fever or bloody diarrhea occurs, patients must contact their healthcare provider immediately.

If rifaximin is being used for treating irritable bowel syndrome, and symptoms return after completing the treatment course, patients must contact their healthcare provider.

Patients must complete the entire course of rifaximin treatment, even if they feel better, as stopping too soon or skipping doses may result in incomplete eradication of the infection, leading to antibiotic resistance.

Patients taking rifaximin to prevent hepatic encephalopathy must not discontinue the medication without consulting their healthcare provider, as abrupt discontinuation may trigger encephalopathy symptoms.
