Résumé
Live MMR vaccine may cause disseminated vaccine-virus infection in patients receiving methotrexate, and the immune response may be impaired. Low-dose methotrexate is sometimes judged acceptable in individual cases, but higher doses clearly raise risk.
Ce que signifie cette interaction, en termes simples
Measles mumps and rubella vaccine live and Methotrexate are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Pourquoi elle survient
Methotrexate suppresses lymphocyte proliferation, allowing replication of live attenuated viruses.
Conduite à tenir
Avoid live MMR during methotrexate therapy; vaccinate at least 4 weeks before starting if possible. Any decision to vaccinate on low-dose methotrexate should be specialist-led.
