Summary
Dexamethasone can induce CYP3A4, which is the main metabolic route for triazolam. Triazolam concentrations may fall, reducing its hypnotic effect, particularly with prolonged dexamethasone courses.
What this interaction means in plain words
Dexamethasone and Triazolam 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
Dexamethasone induces CYP3A4, increasing the metabolic clearance of triazolam.
What to do
Monitor for reduced sedative efficacy during prolonged dexamethasone therapy. Increase the triazolam dose cautiously if needed, and reassess the dose when dexamethasone is stopped.
