What does it do?

Rifaximin is an antibiotic belonging to the rifampicin class, primarily used to treat localized bacterial infections in the intestine. It is effective against both gram-positive and gram-negative bacteria, helping to control infections in the gastrointestinal tract.

Rifaximin inhibits bacterial RNA synthesis, preventing bacterial proliferation. As a result, the number of harmful bacteria in the intestine decreases, alleviating symptoms of infection.
