Sibofix 550 mg Tablet

Sibofix 550 mg Tablet is a prescription antibiotic tablet that contains 550 mg of rifaximin in each tablet. It belongs to the rifamycin class of antibiotics and is used to treat certain gut-related bacterial conditions, including traveler’s diarrhea caused by specific bacteria and, in some patients, to help reduce the risk of hepatic encephalopathy recurring. The Sibofix 550 mg Tablet is taken by mouth and works in the intestine rather than being absorbed much into the bloodstream.

How it works: Rifaximin works by stopping certain bacteria from making the proteins they need to grow and survive. Since Sibofix 550 mg Tablet stays mainly in the gut, it acts locally in the intestine where the infection or bacteria-related problem is occurring.

Sibofix 550 mg Tablet is a higher-strength rifaximin tablet, so it is usually chosen when a doctor wants a full 550 mg dose in one tablet for a specific approved use. Because there are no other strengths or forms listed for this brand, this product fits standard adult regimens that call for 550 mg per dose, rather than a lower-dose starter version.

• Traveler’s diarrhea caused by noninvasive E. coli
• Prevention of recurrent hepatic encephalopathy
• Bacterial overgrowth-related intestinal symptoms when prescribed
• Other doctor-directed gut bacterial infections

• Swallow the Sibofix 550 mg Tablet whole with water.
• Take it exactly at the times your doctor prescribes, even if you start feeling better.
• It can usually be taken with or without food unless your prescriber tells you otherwise.
• Do not crush, split, or chew the tablet unless your pharmacist or doctor says it is okay.
• If you miss a dose, take it when you remember unless it is almost time for the next one.
• For traveler’s diarrhea, treatment is typically short-term and should not be continued longer than prescribed.

Each Sibofix 550 mg Tablet provides 550 mg of rifaximin per tablet. Depending on the condition being treated, this strength may be taken once, twice, or three times daily, and the maximum daily amount is determined by the prescribed regimen for that specific use. Your doctor decides the correct dose and duration based on your diagnosis, age, liver function, and other medicines.

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