What the FDA labels say
From the Fluticasone (FLUTICASONE PROPIONATE DISKUS) label · effective 2026-05-14
Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended.
Drug Interactions with Strong Cytochrome P450 3A4 Inhibitors The use of strong cytochrome P450 3A4 (CYP3A4) inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with Fluticasone Propionate DISKUS is not recommended because increased systemic corticosteroid adverse effects…
The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with Fluticasone Propionate DISKUS is not recommended because increased systemic corticosteroid adverse effects may occur.
Ritonavir A drug interaction trial with fluticasone propionate aqueous nasal spray in healthy subjects has shown that ritonavir (a strong CYP3A4 inhibitor) can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology ( 12.3 )] .
Inhibitors of Cytochrome P450 3A4 Fluticasone propionate is a substrate of CYP3A4.
From the Cyclosporine (Neoral) label · effective 2026-08-10
…in perfusion > decrease in tubular function Increased uptake of Indium 111 labeled platelets or Tc-99m in colloid Therapy Responds to decreased cyclosporine Responds to increased steroids or antilymphocyte globulin A form of a cyclosporine-associated nephropathy is characterized by serial deterioration in renal function and morphologic changes in the kidneys.
In the event of severe and unremitting rejection, when rescue therapy with pulse steroids and monoclonal antibodies fail to reverse the rejection episode, it may be preferable to switch to alternative immunosuppressive therapy rather than increase the Neoral dose to excessive blood concentrations.
Predisposing factors, such as hypertension, hypomagnesemia, hypocholesterolemia, high-dose corticosteroids, high cyclosporine blood concentrations, and graft-versus-host disease, have been noted in many but not all of the reported cases.
