概要
Live zoster vaccine relies on replication of the attenuated varicella zoster virus to produce an immune response. Antivirals active against this virus can suppress replication and may reduce vaccine effectiveness.
この相互作用をわかりやすく説明すると
Famciclovir and Zoster 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.
なぜ起こるのか
Famciclovir's active metabolite penciclovir inhibits viral DNA polymerase and may suppress replication of the live attenuated vaccine virus.
対処法
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 or consider the non-live recombinant zoster vaccine.
