Xifaxan

Name of the generic: rifaximin [rif-AX-imin -AX-imAXEEE “rif-AX-iAX-imin”
The class of drug: miscellaneous antibiotics

What is Xifaxan?

Xifaxan can be described as an antibiotic that fights bacteria, specifically within the intestinal tract.

Rifaximin differs from other antibiotics since it is absorbed by your stomach and then into the intestines without being taken into the bloodstream. Since rifaximin only treats the intestinal tract, it does not treat other organs of the body.

Xifaxan helps treat diarrhoea in travellers, which is the result of Escherichia coli (E. coli) in children and adults that are at least 12 years old. Most people contract the infection through eating food or drinking fluids affected by the E. coli bacteria.

Xifaxan can also be employed to manage IBS, also known as irritable IBS (IBS), in adults whose primary symptoms are diarrhoea.

Xifaxan can also be utilised to reduce the risk of brain function loss in patients suffering from liver disease. Brain function is affected when the liver is not working and is unable to eliminate toxic chemicals from your body.

Warnings

It is not recommended to take Xifaxan if you are sensitive to rifaximin or other drugs like rifabutin (mycobutin), rifampin (rifater, rifadin, rifamate), or the drug rifapentine (priftin).

Before taking Xifaxan, inform your doctor that you have liver disease, diarrhoea that is accompanied by fever, or diarrhoea that's liquid or contains blood.

Use Xifaxan for the entire prescribed duration. The symptoms might improve after the infection is completely gone. Rifaximin is not a treatment for a viral infection, such as an illness like the flu or common cold, or any type of diarrhoea caused by viruses.
