Summary
Systemic corticosteroids can blunt the antibody response to non-live vaccines such as anthrax vaccine, so protection may be reduced. The vaccine is not live, so there is no added infection risk, and it is not a true contraindication.
What this interaction means in plain words
Anthrax vaccine and Methylprednisolone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Corticosteroid-induced immunosuppression suppresses lymphocyte activation and antibody production after vaccination.
What to do
If feasible, vaccinate before starting immunosuppressive corticosteroid doses or delay until the dose is reduced. If vaccination cannot be delayed, give it anyway, as it is still indicated for exposure risk, and consider checking antibody response.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
