Sintesi

This combined live vaccine contains four attenuated viruses that may replicate unchecked in patients on methotrexate, risking disseminated infection. Vaccine effectiveness may also be reduced.

Cosa significa questa interazione in parole semplici

Measles mumps rubella and varicella 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.

Livello di evidenza: Moderate

Perché avviene

Methotrexate-induced immunosuppression impairs clearance of live attenuated viruses.

Cosa fare

Do not administer during methotrexate therapy; give at least 4 weeks before starting treatment when possible, or use separate non-live alternatives where available.
