Summary
Live measles vaccine is generally avoided during significant systemic immunosuppression because of reduced response and the risk of uncontrolled vaccine virus replication. Topical dexamethasone-tobramycin delivers little systemic steroid, so the practical risk is small unless absorption is extensive.
What this interaction means in plain words
Dexamethasone-tobramycin and Measles vaccine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Corticosteroid immunosuppression can impair control of live attenuated virus and reduce immunogenicity, but topical use gives low systemic exposure.
What to do
Short-term topical use does not usually require delaying the vaccine. If high-dose systemic steroids are used, defer live vaccines until steroid therapy has been stopped for the interval recommended in local guidance.
