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 intranasal influenza vaccine contains live attenuated virus, and corticosteroids can impair the control of vaccine virus replication and reduce the immune response. With topical dexamethasone-tobramycin the systemic exposure is typically low, so the risk is mainly theoretical unless absorption is substantial.
What this interaction means in plain words
Dexamethasone-tobramycin and Influenza virus vaccine quadrivalent intranasal 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-mediated immunosuppression may reduce vaccine response and permit greater live-virus replication, but systemic exposure from topical use is low.
What to do
Topical use for a short course generally does not require delaying the vaccine. If systemic or prolonged high-dose steroids are used, give the inactivated influenza vaccine instead.
