Summary
Imatinib may inhibit CYP3A4 and increase systemic fluticasone exposure. With prolonged use this could cause corticosteroid effects such as Cushingoid features and adrenal suppression, though intranasal dosing has low systemic exposure.
What this interaction means in plain words
Fluticasone intranasal and Imatinib have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
