I am so glad i found your post! My 19 year old daughter has POTS. she has had it since 15. She has been on Florinef since. This past year at college everything got worse for her. We went to an adult electrophsyologist in June and she was placed on a beta blocker (Toprol) what a nightmare that med was for 4 weeks! Then a week ago she was placed on Theadur. My child can not move, sleep, eat. Her stomach has been a mess and her heart rate runs 130 to 180 when she is up. I have decided to take her off the theadur and put her back on the florinef. she also wears compression stockings now. any advice would be great.
