high blood pressure
"Losartan is poison and I hope anyone taking it at least monitors their improvement if any vs. the side effects...because they sneak up on you.  I believe this medication will do much more harm than good, so please be careful...I took it because Lisinopril gave me a cough.  I gave it 3-full months and during that time, I became very ill.  Extreme fatigue, headaches, sore back, weakness in my legs that was very scary.  I felt like I had the flu daily and I thought it might be another medication I was on, but I tested myself by stopping the other med's and nope...the symptoms still remained.  I was so exhausted all the time, I could hardly get through my day and had to take daily naps.  I slept very deeply with vivid dreams.  Never ever again!"
