Stopped florinef (fludrocortisone) 0.5 mg prescribed 4 low BP & dizzy spells d/t edema, abd pain, and gain of 7 lbs after two doses. Helped BP & dizziness though. Now urinating clear urine like crazy q 1/2 hr. Normal?

Normal. You were under a fluid retaining effect of Florinef (fludrocortisone) based on your report of weight gain of 7 pounds and swelling. When you stopped it, the fluid started to get mobilized i.e. Started to leave your body. You need to work with your doctor on replacement of Florinef (fludrocortisone) or using a lower dose. Your 0.5 mg dose is unclear to me. The tab is 0.1 mg. This means you are taking 5 pills/day or you mean 0.05mg?
Eliminating. Eliminating excess fluid yes normal but back to where you started before long. Did you discuss with your doctor.
