My 17 year old daughter started taking Asmanex about two months ago and we are wondering if the very unusual activity she's experienced with her menstrual cycle this month might be related to the drug. With a few days respite scattered here and there, she's basically had a period that has lasted all of the month of November. In spite of the fact that we are aware that some irregularity is to be expected in teens, especially when they are under stress, this development is quite unusual for her. Anyone else experienced this with Asmanex?
