Deflazacort and Measles mumps and rubella vaccine live: contraindicated interaction.

Last updated

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

The live attenuated MMR viruses may replicate excessively in patients immunosuppressed by deflazacort, risking vaccine-strain disease. The immune response may also be reduced.

What this interaction means in plain words

Deflazacort and Measles mumps and rubella vaccine live 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.

Evidence level: High

Why it happens

Glucocorticoid immunosuppression impairs control of live attenuated viruses and reduces vaccine immunogenicity.

What to do

Avoid during immunosuppressive corticosteroid therapy; give at least four weeks before starting steroids or after stopping for the interval in labeling. Check immunity and consider immunoglobulin after exposure.
