Summary
Corticosteroids can blunt the immune activation on which nivolumab depends, though they are also the standard treatment for immune-related adverse events. Use at physiological doses or for managing toxicity is acceptable, whereas high-dose prophylactic or prolonged use may reduce efficacy.
What this interaction means in plain words
Dexamethasone and Nivolumab 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.
Dexamethasone belongs to Endocrine; Nivolumab belongs to Oncology.
Why it happens
Pharmacodynamic antagonism: glucocorticoid immunosuppression opposes T-cell mediated antitumor activity enabled by PD-1 blockade.
What to do
Avoid unnecessary corticosteroids before or during nivolumab. Use dexamethasone when needed for immune-related adverse events or supportive care at the lowest effective dose.
