We report a combination of precocious pseudopuberty and adrenal insufficiency in a 4 year-old boy who had received an off-label 'appetite stimulant' syrup and excessive virilization in a 2 year-old girl who had received the same medication. Both patients presented with excessive virilization for a period of approximately 1-2 years. The syrup contains cyproheptadine and methandienone, a derivative of testosterone. Both cyproheptadine and methandienone were responsible for severe adrenal suppression in the boy. Methandienone undoubtedly caused precocious virilization in both children. Cessation of the syrup led to partial regression of virilization in both children and normalization of adrenal reserve function in the boy.
