• Strong Cytochrome P450 3A4 Inhibitors (e.g., ritonavir): Use with caution.

After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased.

Caution should be exercised when considering the co-administration of PULMICORT FLEXHALER with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.7) ] .

When such an infection develops, it should be treated with appropriate local or systemic (i.e., oral antifungal) therapy while treatment with PULMICORT FLEXHALER continues, but at times, therapy with PULMICORT FLEXHALER may need to be interrupted.

• Adrenal Dysfunction : Carefully monitor patients receiving voriconazole and corticosteroids (via all routes of administration) for adrenal dysfunction both during and after voriconazole treatment.

Patients receiving voriconazole and corticosteroids (via all routes of administration) should be carefully monitored for adrenal dysfunction both during and after voriconazole treatment.

Monitor for potential adrenal dysfunction when voriconazole is administered with other corticosteroids [see Warnings and Precautions (5.8) ].

Adrenal insufficiency has been reported in patients receiving azoles with or without concomitant corticosteroids.

In patients receiving azoles without corticosteroids adrenal insufficiency is related to direct inhibition of steroidogenesis by azoles.
