摘要
Live varicella vaccine depends on replication of the attenuated virus to generate immunity. Antivirals active against varicella zoster virus can suppress this replication and may blunt the immune response to the vaccine.
用白話說明這項交互作用的意義
Famciclovir and Varicella virus vaccine live 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.
為什麼會發生
Famciclovir's active metabolite penciclovir inhibits viral DNA polymerase and may suppress replication of the live attenuated vaccine virus.
處置方式
Stop famciclovir at least 24 hours before vaccination and avoid restarting it for 14 days afterward if clinically possible. If antiviral therapy is essential, delay the vaccine.
