Rifakem 400 mg Tablet

Rifakem 400 mg Tablet is a prescription antibiotic tablet that contains 400 mg of rifaximin in each tablet. It belongs to the rifamycin class of antibiotics and is used for certain bacterial infections, including infections in the gut where the medicine works locally in the intestine. Rifakem 400 mg Tablet should be used only when a clinician has decided it is appropriate for your condition.

How it works: Rifaximin in Rifakem 400 mg Tablet stops bacteria from making the proteins they need to grow and multiply. Because this tablet is taken by mouth and acts mainly in the gut, it can reduce certain bacteria in the intestines with limited absorption into the bloodstream.

Rifakem 400 mg Tablet is a higher-strength tablet, so it is meant for patients whose doctor has assessed that a 400 mg dose is suitable. Because there are no other strengths or forms listed for this brand here, this product fits dosing plans where a clinician wants a full 400 mg tablet strength rather than a lower-dose option.

• Traveler’s diarrhea caused by susceptible bacteria

• Finish the full course even if you start feeling better before the tablets are gone.

Each Rifakem 400 mg Tablet provides 400 mg of rifaximin per tablet. How often you take it depends on the condition being treated; some regimens use one tablet once daily or a tablet taken multiple times per day, but the exact schedule and the maximum daily amount must be set by your doctor. Do not change the dose yourself, because the right dosing for Rifakem 400 mg Tablet depends on your diagnosis and medical history.
