Calcium Channel Blokers (Dilacor), Vase dilators (Monisol), Beta Blockers (Dilatrend) and
I hope that you had done a mistake and
your creatinine is 1.98 in any case a bit high, your kidneys are at risk, particularly with a such low BP.
Potassium is a bit high, Alcadatone can be the reason for it, or any sodium reduced salt that you may take.
My first advise is check with your dr.
If this were not possible I would:
1) Try to drink more, this will enhance your creatinine.
