Summary
Corticosteroids at above-physiologic doses may blunt the immune response to the live attenuated dengue vaccine. Topical or ophthalmic dexamethasone has minimal systemic immunosuppression, so the effect there is unlikely to matter.
What this interaction means in plain words
Dengue vaccine and Dexamethasone-tobramycin 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 immune response.
What to do
No action is needed for local use with low systemic exposure. If systemic corticosteroids are required, defer vaccination until therapy is reduced or stopped.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
