Sedative/hypnotics triazolam, oral midazolam ↑ triazolam ↑ midazolam Co-administration contraindicated due to potential for extreme sedation and respiratory depression [see Contraindications (4) ] .

Serotonin receptor 1A agonist/ serotonin receptor 2A antagonist flibanserin ↑ flibanserin Co-administration contraindicated due to potential for hypotension, syncope, and CNS depression [see Contraindications (4) ] .

Corticosteroids primarily metabolized by CYP3A betamethasone, budesonide, ciclesonide, dexamethasone, fluticasone, methylprednisolone, mometasone, triamcinolone ↑ corticosteroid Co-administration with corticosteroids (all routes of administration) of which exposures are significantly increased by strong CYP3A inhibitors can increase the risk for Cushing’s syndrome…

Alternative corticosteroids including beclomethasone, prednisone, and prednisolone should be considered.

Therefore, coadministration of azelastine hydrochloride and fluticasone propionate nasal spray and ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects.

• Ritonavir: Coadministration is not recommended.

Therefore, coadministration of fluticasone propionate and ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects.

Use of Cytochrome P450 3A4 Inhibitors Ritonavir and other strong cytochrome P450 3A4 (CYP3A4) inhibitors can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .

Use caution with the coadministration of azelastine hydrochloride and fluticasone propionate nasal spray and other potent CYP3A4 inhibitors, such as ketoconazole [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .
