Summary
Nefazodone is a strong CYP3A4 inhibitor and can raise triamcinolone exposure. This may lead to Cushingoid features and adrenal suppression, particularly with repeated or depot dosing.
What this interaction means in plain words
Nefazodone and Triamcinolone can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Inhibition of CYP3A4 reduces triamcinolone clearance.
What to do
Avoid the combination if possible, or use a corticosteroid less dependent on CYP3A4. If used together, give the lowest effective triamcinolone dose and monitor for steroid excess and adrenal suppression.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
