 [ Symptoms ] i have high potassium and dr recently dc hctz and lisinopril but left me on spironolactone is this right  type 1 diabetic 21 years heart stent stage 3 kidney disease 29 yrs old female [ Disease ] to get the best answer to your question i would suggest picking up the phone and discussing your concerns with your health care provider he or she will be happy to explain the rationale behind leaving you on spironolactone while discontinuing the other drugs my hunch is that your provider feared your potassium might dip too low after withdrawing the hctz hydrochlorothiazide which can strip potassium from your system by leaving you on a potassium sparing diuretic water pill like spironolactone perhaps your provider thinks your potassium will level out however that is just a guess obviously i can not read your provider is mind as i said your best bet is to ask your provider directly wishing you all the best
