A substitute contains the same active ingredient (salt), in the same strength, as Riflect 400 mg Tablet. The medicine inside is the same — the brand name, manufacturer and price are what differ.
All medicines sold in India, branded or generic, must meet the quality standards set by the national drug regulator (CDSCO). A lower price does not mean lower quality.
Please confirm with your doctor or pharmacist before switching brands — they will check that the strength and form match your prescription.
Riflect 400 mg Tablet contains Rifaximin (400mg). It belongs to the Antibacterial agent class of medicines.
Treatment of Infectious diarrhea
Riflect 400 mg Tablet is an antibiotic. It works by killing the ammonia-producing bacteria in the digestive tract. This treats your infection and relieves symptoms of hepatic encephalopathy (agitation, confusion, muscle problems). This also helps reduce the recurrence of episodes of hepatic encephalopathy.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Riflect 400mg Tablet may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Riflect 400mg Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause vomiting, severe loose motions and nerve symptoms. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Riflect are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Finish the whole course even after you feel better. Do not drink any alcohol while taking metronidazole, ornidazole or tinidazole, or for the period after the course that your doctor states — the combination causes severe flushing, vomiting and a racing heart. Report severe or watery loose motions during or after the course rather than treating them yourself. Tetracyclines stain developing teeth and are avoided in young children and in pregnancy. Antibiotics do not work against colds, flu or most sore throats, which are caused by viruses.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack.
Antacids, iron, zinc and calcium reduce the absorption of tetracyclines — separate them by a couple of hours. Tell your doctor if you take a blood thinner.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Riflect 400mg Tablet reduces the risk of overt hepatic encephalopathy (HE) recurrence in patients with liver disease. It may cause reddish discoloration of urine. This is normal and harmless. Stop taking Riflect 400mg Tablet and inform your doctor if you have severe diarrhea during or after using Riflect 400mg Tablet. Finish the full course of the medication, even if you feel better.
