Summary
Nirmatrelvir is a strong CYP3A4 inhibitor, so fluticasone exposure may increase. This could lead to systemic corticosteroid effects, though a short Paxlovid course limits the risk for inhaled fluticasone.
What this interaction means in plain words
Fluticasone and Nirmatrelvir 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.
Fluticasone belongs to Respiratory; Nirmatrelvir belongs to Anti Virals.
Why it happens
Nirmatrelvir inhibits CYP3A4, reducing fluticasone clearance.
What to do
