I was on Lisonpril for three months, then switched to Diovan due to the cough caused by Lisonpril...but at least I could read that side effect in the prescription warning. There was no warning of weight gain with my current prescription of 1/2 pill a day(180mg). I have been on Diovan for three months and have cut caffeine and increased my exercise. At first the drug lowered my bp from 150/102 to 125/85 which I thought was great..but my bp has been slowly increasing. I started at 130 lbs and am now 150lbs...I have gained over 20lbs since starting the drug. I've experienced painful gas and insomnia. I am only 41 and two flights of stairs and I'm out of breath. A drug you take to make you feel better shouldn't make you feel worse. I'm going to try to use more natural methods.
