Chlorthalidone
high blood pressure
"I am male mid-50s and have taken many hypertension meds, most with some level of side-effects.  I have settled on 2 with positive side-effects that work okay (captopril and amlodipine), and chlorthalidone with no side-effects that I am aware of and which pounds the numbers down the most.  One of the most highly regarded medicine trials, called ALLHAT, found this to be the best.  Not sure why it's not one of the first to be prescribed."
