Recurrent hypoglycaemia in a toddler on β-blocker therapy

Abstract

AbstractHypoglycaemia is a well-known side effect of Propranolol. We described the case of a child presenting severe and recurrent Propranolol-induced hypoglycaemia. Those episodes were not related to prolonged fasting and were associated with only mild ketosis. Thus, therapy with β blockers may not only aggravate classical ketotic hypoglycaemia but also interfere with glucose metabolism.
