Résumé
The intranasal influenza vaccine contains live attenuated virus, which may replicate excessively in patients taking methotrexate and cause influenza illness. The immune response may also be reduced.
Ce que signifie cette interaction, en termes simples
Influenza virus vaccine quadrivalent intranasal 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 antimetabolite immunosuppression impairs control of the attenuated live virus.
Conduite à tenir
Avoid the intranasal live vaccine in patients on immunosuppressive methotrexate regimens; use an inactivated injectable influenza vaccine instead.
