high blood pressure
"I've been on Losartan for about 12 months. At first this medicine lowered my BP to about 130/88. Over the 12 month period, my back by my kidney area felt like someone kicked it. Then, I was experiencing major depression off and on for months, nausea, extreme sensitivity to sound that I would startle easy, along with failing memory/concentration as my memory before the Losartan was pretty sharp.  I also found out during that 12 month period that I now have big gallstones and diverticulosis. 
These symptoms didn't appear until AFTER I started taking the Losartan daily for 12 months. Now, the Losartan is not working on my BP, so my doctor wants to try another medication on me, with of course more side effects. Not recommended."
