Summary
Systemic corticosteroids can blunt vaccine immune response. This combination is mainly applied topically or to the eye, so systemic exposure is minimal and a meaningful effect on the inactivated vaccine is unlikely.
What this interaction means in plain words
Anthrax vaccine and Dexamethasone-neomycin-polymyxin 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 could blunt vaccine response, but only with significant systemic exposure.
What to do
No change is needed for ophthalmic or topical use. Reassess vaccination timing if prolonged or high-dose systemic steroids are given.
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?
