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.
