One of my patients gave me this address:it is quite interesting. May I give you our new information on the web : www.med.jhu.edu/pedendo/cah . It deals only with 21-hydroxylase deficiency. As to the present case,its a difficult call.On the one hand,you do not want to give too much steroid:it may impair final height.On the other hand,you want to be safe. A physician should never give advice without seeing the patient(unless he knows the patient and family well).It was probably OK to give extra dose,but I would see the MD in order to check on the fainting.
