No, Martha, my late son's excessively high BP was not attributed to too much florinef. He died of a sudden type of undiagnosed brain infection (similar to menigitis), and the resulting adrenal crisis (VERY long story). His blood pressure had never been a problem before that. However, 2 florinef tablets for a 2 & a half year old DOES seem high to me - is this the norm for others, too?? I can understand that a consistantly high BP would be cause for alarm for you; I would question your endo about it, and see if you can find out what other endos are doing - for comparison (and ammunition!) Hope this helps. God's blessings.
