Hi, just having probs with blood pressure, it was low, so the drs took me off Cardizem CD and put me on fludrocortisone, up to 0.3mg daily. Was stable about 6 months, then my BP jumped to 160/90, was in hospital overnight (about 3 monts ago) and it came back down to normal. Fludrocortisone changed down to 0.2mg and BP stabilised. I have been off the florinef for about a week now,as a test with drs ok, and currently (in bed at almost 4am!) my BP is sitting at 159/116 with a heart rate of 75. I am 18 1/2 years post heart transplant, current ag is 32.
