No, it's not the potassium- it's the florinef. Have you been getting good relief from it (the florinef)? If so, I'd go down to 1/4 tablet rather than stopping all together. Florinef is known to raise BP. I had the same situation. It gave me good relief UNTIL my BP got too high. Our docs have given us permission to go up and down on dosage as needed. It's really smart to periodically check your BP as it can inexplicably (silently) shoot up with the florinef. BTW, florinef can drain your body of potassium. It's good to replace it sometimes. At a low dose like you are taking, it's usually not necessary. Is your potassium a prescription? Be sure to carefully monitor that as a low/high can affect HR, etc. Let us know how you do. Julie I do have a Potassium prescription from when I was diagnosed with Meniere's (incorrectly), but just took OTC Potassium supplements. My BP was up in the 120's yesterday and 130's this morning, but when I started feeling bad I checked and it was 147/88. That's a new one for me. Thanks for the advice!
