I take hydrochlorothiazide (a diuretic) to keep BP low. My first dose of Welchol (3 tablets at mealtime) produced excruciating pain in my feet after about 2 hours. Lesser pains progressed up my legs in the next few days until they reached my hips. Now 2 weeks after and no more Welchol, I don't have any more pain. I'm very alergic to Welchol. Are there others? Does HCZT have any bearing on this?
