Does anyone feel this way or suspect this? If so, which medication are you taking? I take a medication called Prinzide, which is a combination of Lisinopril (Ace Inhibitor) and Hydrochlorothiazide (diuretic). I can't pinpoint exactly when my hair loss started but it very well could have been approx 4 1/2 years ago when I started these medications. At the time I had switched from a brand-name birth control pill to a generic, and this caused me to gain 30 lbs. ALL of my health issues began that year right after that, including mildly elevated blood pressure that I had never experienced before. I especially wonder if the diuretic is causing me to become depleted of certain vitamins/minerals. The only level I have had checked so far is Vitamin D, which was low. But I have not yet had my Vitamin B and Zinc checked, which I have heard can contribute to hair loss.
