Summary

Nefazodone is a strong CYP3A4 inhibitor and may raise systemic exposure to corticosteroids. Prednisone is affected to a lesser extent than methylprednisolone, but increased corticosteroid effects and adverse reactions are possible.

What this interaction means in plain words

Nefazodone and Prednisone 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.

Evidence level: Moderate

Why it happens

Inhibition of CYP3A4-mediated metabolism by nefazodone reduces corticosteroid clearance.

What to do

Monitor for corticosteroid adverse effects such as hyperglycemia, fluid retention and mood changes, and reduce the prednisone dose if they appear. Consider an alternative antidepressant for prolonged use.

What to ask your pharmacist
