Hi I am 28 yrs of age and I've been taking lisinopril (5 mg) for about 2 years now. At the beginning it seemed all well and I was glad that I'd been prescribed with a nice drug. But as the days went by I started to feel the VENOMIC effects of this DRUG. Slowly this venom was killing me from within, at the beginning i thought some other reasons behind and didn't give much attention to the drug, but later the symptoms just worsened and a time came when i could no longer take this medication. I recently consulted a different physician and he has changed me to atenolol+amlodipine. It seems to be working nicely.
