Zimigut 400 is a prescription antibiotic indicated for gastrointestinal infections and related gut conditions. Its active ingredient is Rifaximin (400 mg), an FDA-approved, minimally absorbed antibiotic that belongs to the Rifamycin group. Intas Pharmaceuticals Ltd. manufactures it at GMP-compliant facilities.
Rifaximin 400 mg tablet acts locally in the intestines by binding to bacterial RNA polymerase and stopping bacterial growth. In this way, it helps relieve infection-associated diarrhea and related intestinal symptoms. This gut infection antibiotic is used in the management of Traveler’s Diarrhea, Irritable Bowel Syndrome with Diarrhea (IBS-D), and Hepatic Encephalopathy.
Because Zimigut is a high-dose prescription medicine, it must be used only under medical supervision. It is generally prescribed for 3 to 14 days, 3 times daily, depending on the condition being treated. If the diarrhea becomes bloody, discontinue the treatment and seek medical advice. Take a missed dose as soon as remembered, unless the next dose is due soon. In case of overdose, stop the medicine and consult a healthcare professional.
Common side effects of Zimigut include gas or bloating, headache, nausea, mild constipation, and dizziness. These are usually mild and temporary. However, medical attention is recommended if they continue for a prolonged period. Before using this medicine, you should inform your doctor about any allergy to Rifamycin antibiotics, as well as any serious liver or kidney problems.
Caution is also required when using it along with medications such as Warfarin and Cyclosporine. Zimigut tablets should not be taken for non-bacterial diarrhea. Furthermore, store the tablet at a temperature below 30°C. Protect it from moisture, direct sunlight, and heat. Keep it out of the reach of children and pets, and discard it after expiry.
