Resumo
Live BCG is a viable attenuated bacterium, and antibacterial drugs active against mycobacteria can kill the vaccine organisms and reduce the immune response. Dapsone has activity against mycobacteria, so vaccine efficacy may be impaired.
O que esta interação significa em palavras simples
Bcg vaccine live and Dapsone can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Por que acontece
Dapsone's antimycobacterial activity may inactivate the live attenuated BCG organisms, reducing vaccine take.
O que fazer
Defer BCG vaccination until dapsone therapy is finished, or revaccinate later if it was given during treatment. For intravesical BCG, avoid concurrent antimycobacterial therapy.
