Introduction to Myrifa

Myrifa is a medication primarily used to treat certain gastrointestinal conditions. It is known for its effectiveness in managing traveler's diarrhea, irritable bowel syndrome with diarrhea (IBSD), and hepatic encephalopathy. Myrifa is also used off-label for conditions like small intestinal bacterial overgrowth (SIBO) and C. difficile-associated diarrhea.

Composition of Myrifa

The active ingredient in Myrifa is Rifaximin. This compound works by inhibiting bacterial RNA synthesis, which prevents the growth and replication of bacteria in the gut. Since Myrifa has minimal systemic absorption, it specifically targets gut infections without significantly affecting other parts of the body.

Precautions of Myrifa

Myrifa should be used cautiously in individuals with a history of liver disease. It is not recommended for those with hypersensitivity to Rifaximin or any component of the formulation. Additionally, it should not be used for the treatment of systemic infections. Pregnant or breastfeeding women should consult a healthcare provider before using Myrifa.
