http://www.medications.com/effect/view/24443 Just started taking lisinopril (2nd dose today, 20 mg) for HBP. I have had HBP for about 15 years. I was taking HCTZ, a diuretic, plus atenelol. That stuff makes you feel miserable, depressed, paranoid along with major constipation and very low potassium bl Sat, 20 Oct 2007 11:05:43 -0400 http://www.medications.com/effect/view/24443?item=2488 It's great to be optomistic....but have you read the pages and pages of side effects to this drug? (including my own) I wouldn't take any chances. Stand up to your doctor and just say you WILL NOT continue to this drug. The side effects will only get worse http://www.medications.com/effect/view/24443?item=2488
