I was on Lisinopril 12.5 mg. for about 1 1/2 years for high blood pressure. I experienced dizziness, blurred vision, lack of concentration, scary felling with my heart, cramps in legs, gout. A couple of days ago I felt really bad, I went to the doctor who discovered that my blood pressure was too low. I told her it has been normal for a year. Why would the doctor keep me on Lisinopril? She lowered the dose to 10mg. I don't like using prescription drugs. What to do!
