Hi Lynn, I hope you don't mind my asking but I always do when I find someone who has a teenage boy with CAH. My son is 14. Could you please tell me how tall your son is and if he has stopped growing? If this is too intrusive, feel free not to respond. My son is also fine on Cortef. However, my daughter has been on prednisolone (Pediapred) since she was a baby (she is 8). Thanks!
