Adrenal suppression with intranasal betamethasone drops

Abstract

Intranasal betamethasone sodium phosphate drops (Betnesol) are frequently used to relieve nasal congestion due to polyposis. We report a case of significant hypothalamic-pituitary-adrenal suppression secondary to the long-term use of intranasal betamethasone drops. This case emphasizes that the topical application of potent corticosteroids may produce systemic effects.
