I am just another CAH mom but the drug is growth. It is a shame that the ped endo doctor was not able to control the CAH so that this drug was not necessary. I would assume that the cortisol was underdosed because a child with a late diagnosis or misdiagnosis would have a growth problem. They would grow fast but the bones would fuse too early and then they would end up short in statue. preston@kreative.net Roberta
