Summary
Nefazodone is a strong CYP3A4 inhibitor and may raise enzalutamide concentrations, increasing risks such as seizures and fatigue. Enzalutamide may in turn lower nefazodone levels and reduce antidepressant effect.
What this interaction means in plain words
Enzalutamide and Nefazodone 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.
Why it happens
Nefazodone inhibits CYP3A4 while enzalutamide induces it, with opposing effects on each drug's metabolism.
What to do
Monitor for enzalutamide adverse effects and for loss of antidepressant response; consider an alternative antidepressant.
