Summary
Verapamil is a moderate CYP3A4 inhibitor and may increase triamcinolone exposure. This may lead to corticosteroid excess effects, especially with repeated or long-term triamcinolone treatment.
What this interaction means in plain words
Triamcinolone and Verapamil 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.
Triamcinolone belongs to Endocrine; Verapamil belongs to Cardiovascular.
Why it happens
Verapamil inhibits CYP3A4-mediated metabolism of triamcinolone, reducing its clearance.
What to do
Monitor for signs of corticosteroid excess such as Cushingoid features, hyperglycemia and adrenal suppression during prolonged use. Consider reducing the triamcinolone dose or choosing an alternative corticosteroid.
