Resumo
The oral live attenuated cholera vaccine needs viable bacteria to colonize and stimulate immunity. Antibiotics active against V. cholerae could lower the immune response. Rifaximin has activity against many enteric bacteria and acts locally in the gut, where the vaccine strain must establish.
O que esta interação significa em palavras simples
Cholera vaccine and Rifaximin 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
Luminal antibacterial activity in the gut can reduce viability and colonization of the live attenuated vaccine strain.
O que fazer
Do not give the vaccine to patients who have recently had antibiotics; follow the labeled interval after the antibiotic course (14 days is stated in labeling). Delay the vaccine rather than the antibiotic when treatment is needed.
