Hemangiomas tend towards a natural regression. There is however a proliferative phase. Inderal was incidentally discovered to hasten the regression. It is available is a liquid or a tablet. It has been tolerated in infancy, which is where the most targeted proliferative phase happens. Typically it is dosed in a bid fashion at around 1-2 mg/kg/day for 5-6 months. Blood glucose and EKG are often checked pre treatment.
