title: Hypothalamo-pituitary-adrenal axis suppression in asthmatic adults taking high dose beclomethasone dipropionate.
abstract: Inhaled corticosteroids control symptoms of chronic asthma in most patients. Use of drugs such as beclomethasone dipropionate (BDP) and budesonide is being encouraged as the importance of airways inflammation in asthma is increasingly appreciated. Beclomethasone dipropionate is used in doses of up to 2000 micrograms daily (equivalent to eight puffs of Beclorforte inhaler) and the Data Sheet warns that systemic absorption sufficient to cause suppression of the hypothalamo-pituitary-adrenal (HPA) axis may occur in some patients taking 2000 micrograms. HPA suppression to an extent which is clinically relevant has not been reported in asthmatic adults taking lower doses of BDP. We report six cases of HPA hypofunction occurring in patients on long-term treatment with BDP, in a dose of 1500 micrograms daily. Patients taking BDP in a dose of 1500 micrograms daily might be at risk of adrenal crisis and should carry steroid cards unless HPA function has been assessed and found normal.
