Summary
Corticosteroids such as betamethasone suppress immune function, and combining them with ocrelizumab increases the risk of infection, especially at high doses or with prolonged use. Short premedication courses are routine and generally manageable.
What this interaction means in plain words
Betamethasone and Ocrelizumab 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.
Betamethasone belongs to Endocrine; Ocrelizumab belongs to Central Nervous System.
Why it happens
Additive immunosuppression from B-cell depletion by ocrelizumab and broad glucocorticoid-mediated suppression of cellular immunity.
What to do
Use the lowest effective corticosteroid dose and duration, and monitor for infection. Screen for hepatitis B and other latent infections before therapy.
