- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
What happens
An inadequate immunological response to the vaccine, an increased risk of altered immunocompetence and reduced immune response to rabies vaccine with risk of developing rabies
Interaction Deep Dive
Corticosteroids, other immunosuppressive agents or treatments, and immunosuppressive illnesses can interfere with the development of active immunity and predispose the patient to developing rabies. Do not administer immunosuppressive agents during post-exposure prophylaxis, unless essential for the treatment of other conditions. When rabies post-exposure prophylaxis is administered to individuals receiving steroids or other immunosuppressive therapy, it is especially important that serum be tested for an rabies virus neutralizing antibody (RVNA) titer to ensure that an adequate response has developed. An individual’s risk of developing rabies must be carefully considered before deciding to discontinue vaccination. Moreover, the use of corticosteroids to treat life-threatening neuroparalytic reactions carries the risk of inhibiting the development of active immunity to rabies. It is especially important in these cases that the serum of the patient be tested for RVNA titers. Advice and assistance on the management of serious adverse reactions in individuals receiving rabies vaccines1.
Why it happens (mechanism)
Suppression of the immune system; inhibition of the development of active immunity to rabies by corticosteroids
