Resumo
Intravesical BCG depends on viable mycobacteria to induce a local immune response against bladder cancer. Antibiotics with antimycobacterial activity may reduce BCG viability and therapeutic effect. Rifaximin is minimally absorbed and its systemic exposure is low, so the risk is lower than with systemic antituberculous agents.
O que esta interação significa em palavras simples
Bcg intravesical live and Rifaximin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Por que acontece
Antibacterial activity may reduce viability of the live BCG organisms, though rifaximin has little systemic exposure.
O que fazer
Where possible, defer BCG instillations until the antibiotic course is finished. If rifaximin must continue, monitor response to BCG therapy.
