Has anyone had any problems with raised potassium levels due to spironolactone? My husband has heart failure & after being on spironolactone for 3 months over a year ago, he was taken off it due to high potassium levels. They're now trying it again, he's been on 1/2 tablet since January with the view to increasing it to 1 tablet. Regular blood tests show his starting level was 4.7, it's now 4.9. He's got another blood test next week & then they want to increase the doseage. The normal range is 2.5 to 5.3 (if I'm reading the reports correctly), Im just wondering if his starting level was high if & is it slowly creeping up? Any one know?
Thanks for your help
