Summary
Nicardipine is only a weak CYP3A4 inhibitor, so any increase in systemic fluticasone is expected to be small with intranasal use. Strong inhibitors are the main concern for Cushingoid effects and adrenal suppression.
What this interaction means in plain words
Fluticasone intranasal and Nicardipine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Nicardipine weakly inhibits CYP3A4, which could slightly reduce clearance of absorbed fluticasone.
What to do
No routine change is needed with standard intranasal doses. Watch for signs of corticosteroid excess if used long term at high doses.
