Hydrochlorothiazide / losartan
"For those who are having terrible leg cramps on BP medication. I had the same horrible problem to the point I was screaming my head off at times and could not walk.  It was the HCTZ DIURETIC portion of my bp med that was causing it. NOT the Losartan part.  This will be the same for any BP med that is blended with a HCTZ diuretic because Triamterene did the same thing.  Since I don't really have any medical need for the diuretic, my doctor simply wrote me a script for the Losartan without the diuretic in it. Voila!! no more leg cramps! and my bp is still under control."
