Serious Warnings

Known Drug Interactions
betamethasone budesonide ciclesonide fluticasone methylprednisolone mometasone triamcinolone ↑ corticosteroids 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 and adrenal suppression.
Mechanism: Darunavir prevents the body from clearing budesonide, which can lead to very high steroid levels in the blood. This increases the risk of your adrenal glands not working properly.
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 and adrenal suppression.
Mechanism: The antiviral blocks the natural process your body uses to get rid of budesonide, causing the steroid levels to rise. This can lead to serious side effects like hormone imbalances and adrenal suppression.
(7.4) 7.1 Inhibitors of Cytochrome P4503A4 The main route of metabolism of corticosteroids, including budesonide, a component of SYMBICORT, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4). After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased. Concomitant administration of CYP3A4 may inhibit the metabolism of, and increase the systemic exposure to, budesonide.
Mechanism: Certain medications can slow down how your body breaks down budesonide. This causes the drug to stay in your system longer and reach higher levels.

Mechanism: Itraconazole can slow down the way your body breaks down this steroid, which may cause the steroid to stay in your system longer than usual.
