Rifagut 400 mg Tablet

Rifagut 400 mg Tablet is a prescription antibiotic medicine containing 400 mg of rifaximin in each tablet. It is supplied by Sun Pharmaceutical Industries Ltd. in a strip/box of 10 tablets. Rifagut 400 mg Tablet belongs to the rifamycin class of antibiotics and is used for certain bacterial infections and gut-related conditions where a doctor decides rifaximin is appropriate.

How it works: Rifaximin works mainly inside the intestine by stopping bacteria from making the proteins they need to grow and multiply. Because Rifagut 400 mg Tablet is a tablet taken by mouth, it delivers the medicine through the digestive tract where it can act locally in the gut.

Rifagut 400 mg Tablet is a higher-strength tablet than Rifagut 200 mg Tablet, so it may be chosen when a prescriber wants fewer tablets per dose or a specific total daily amount. Compared with Rifagut 550 mg Tablet, this 400 mg strength can offer more flexible dose adjustment, but it is not a lower-dose starter for everyone; it should be used only when a clinician has assessed the need for this exact strength.

• Traveler’s diarrhea caused by susceptible bacteria
• Irritable bowel syndrome with diarrhea (IBS-D)
• Hepatic encephalopathy prevention or treatment as directed by a doctor

• Take it exactly at the times prescribed; do not change the schedule on your own.
• It can usually be taken with or without food, but follow your prescriber’s directions if meals are part of the plan.
• Do not crush or chew the tablet unless a pharmacist or doctor specifically says it is okay.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.
• Complete the full course if your prescriber says to use it for an infection, even if you feel better sooner.

Each Rifagut 400 mg Tablet provides 400 mg of rifaximin per tablet, and the number of tablets per dose depends on why it was prescribed. It may be taken once, twice, or three times daily depending on the condition, but the exact schedule and maximum daily amount are determined by the doctor. Never use more tablets or take them more often than prescribed for this specific 400 mg strength.

Do not change your dose or stop the medicine without speaking to your doctor.
