That is another question I am going to ask her endo. We had trouble with her levels being too high for a while. We changed to splitting the pill and by adjusting her Cortef. Her levels have never been so excellent now. (knock on wood) This will be another issue to discuss with her endo. I want to know if by splitting the pill had anything to do with this great change. Perhaps someone else can answer the question on why their endo. spits it until I get an answer from my endo. Thanks for the info. Andy.
