Summary
Corticosteroids can reduce the antibody response to rabies vaccine, risking inadequate protection. Because rabies is nearly always fatal once symptomatic, this matters for post-exposure prophylaxis.
What this interaction means in plain words
Methylprednisolone and Rabies vaccine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Corticosteroid immunosuppression impairs the active antibody response to the vaccine.
What to do
Never withhold post-exposure prophylaxis, and give rabies immune globulin when indicated. Check rabies neutralizing antibody titres after the course in patients on immunosuppressive steroids.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
