high blood pressure
"I started taking this medication in combination with Quinapril, which apparently is common (they also make a single pill containing both medicines).  My blood pressure was reduced, though it is hard to say if one medicine was more effective than the other.  However, after taking this, I began having attacks of gout, which I've never had in my life.  This diuretic increases uric acid levels in the bloodstream, which is the cause of gout.  If you are prone to gout or develop it let your doctor know."
