Have been taking Lisinopril (5mg) once a day for almost two months. I'm a 52 y.o. male in good physical condition, 5'11", 200 pounds, work out with weights at least three or four times a week, treadmill work at least twice a week and very little salt intake, no fried foods, and overall healthy eating habits. The doctor told me when I was diagnosed with H.B.P. during a visit for a muscle strain that losing weight or changing diet and excercise weren't options to help with the problem since I was in good shape and eating well already. My blood pressure went down beginning the first week and by the third week was near normal (about 123/78). Great news, you would think........except............. I developed a dry cough and scratchy throat within days of starting the drug and it now persists 24/7 causing a loss of sleep. I have severe itching and small rashes in various places but mostly in creases around joints and between cheeks (yeah, THOSE cheeks). Broke out in a cold sweat, became nauseous, and nearly passed out at work one morning. I guess because of a quick drop in B.P. Have a hard time concentrating and making sense according to others at work. And last but not least, my sex drive is practically non-existent, which is okay I suppose since I haven't been able to get an erection since about three weeks after I started taking this crap. Other than that life is just great! So I stopped taking this stuff two days ago and am hoping to become healthy again once I get whatever this poison is out of my system. I'm willing to live with a little high blood pressure since I felt just fine before the doctor told me I just HAD to take something. I'd rather be healthy and happy with a touch of H.B.P. than sick and impotent with a normal reading.
