What this interaction means in plain words
Dexamethasone and Sorafenib 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; Sorafenib belongs to Oncology.
Why it happens
