I started taking it in 3 months ago to get my blood pressure up a bit so I don't feel like passing out when I stand up. It has done a good job with that, but now when I start to exercise my heart rate jumps into the 150's for a while (still doing warm ups) and then drops below where it should be. Then it recovers and maintains an appropriate reading for the remainder of the workout. Never experienced this prior to taking fludrocortisone. I have gained 2 pounds but don't know if I can attribute that to taking the drug or not.
