Rifaximin - Overview

Rifaximin, marketed under the name Xifaxan, is an antibacterial medication used in the treatment of travelers' diarrhea when a possible infection is proven or strongly suspected to have been caused by bacteria. People who might need a rifaximin prescription can connect with a medical provider through Push Health who can prescribe rifaximin medication, including rifaximin 550 mg and rifaximin 200 mg tablets, when appropriate to do so.

Rifaximin - Uses and Mechanism of Action

Rifaximin prescription medication is a type of antibacterial medication with the primary use being the treatment of noninvasive strains of Escherichia coli causing travelers' diarrhea in adult patients and for some cases of irritable bowel syndrome (IBS) in the setting of small intestinal bacterial overgrowth (SIBO). Rifaximin is a semi-synthetic, non-aminoglycoside compound similar to rifampin. Rifaximin medication is thought to work by inhibiting bacterial RNA synthesis by binding to bacterial DNA-dependent RNA polymerase. Escherichia coli has demonstrated resistance to rifaximin in vitro and the potential for cross-resistance has not been thoroughly analyzed. Rifaximin tablets are poorly absorbed after oral administration and plasma levels of rifaximin are variable and often undetectable. Rifaximin prescription medication is almost exclusively excreted in the feces.

Rifaximin - Cost and Dosage

Rifaximin tablets are expensive, costing over $20 per rifaximin 200 mg tablet at most pharmacies. Fortunately, some insurance plans will cover the cost of a rifaximin prescription and rifaximin coupons are sometimes available online to help reduce the cost even further. Rifaximin 200 mg tablets are typically pink in color and round. For travelers' diarrhea, some prescribers will choose a regimen involving rifaximin 200 mg tablets taken 3 times a day for 3 days orally, with or without food. Rifaximin tablets should generally be stored at 20° C to 25° C but check the package for exact instructions.

Can I Buy Rifaximin Online?

Rifaximin medication requires a prescription before a pharmacy can dispense it in the United States. As a result, one cannot buy rifaximin online or get rifaximin OTC (over the counter) at a pharmacy. The first step is getting a rifaximin prescription from a licensed medical provider. Push Health can connect people who need a rifaximin prescription with a medical provider who can prescribe rifaximin medication, including rifaximin 200 mg or rifaximin 550 mg tablets when appropriate to do so.

Rifaximin - Side Effects

Rifaximin prescription medication can cause side effects but is generally considered safe. Side effects resulting from rifaximin tablet use include headache, stomach and rectal pain, gas, and nausea. Rifaximin is not effective in treating diarrhea with fever or blood in the stool or for treating organisms other than Escherichia coli. People with allergies or a known hypersensitivity to rifaximin should not use the medication. Rifaximin and alcohol should not be used concomitantly. Rifaximin use has been associated with Clostridium difficile-associated diarrhea. Questions about possible side effects related to rifaximin use should be directed to one's pharmacist and medical provider before using rifaximin medication.
