‘Magic mouthwash’ with potent corticosteroid triggers iatrogenic Cushing’s syndrome: case

Topical corticosteroids pose a risk of systemic absorption even as dental treatments, Aussie doctors warn.

Sydney doctors have warned about the increasing use of prescribed ‘magic mouthwashes’ after a 76-year-old woman developed iatrogenic Cushing’s syndrome while using such a rinse. 

She had been on the compounded oral rinse, which contained the potent topical corticosteroid clobetasol propionate, for 12 months after it was prescribed by her oral medicine specialist.
