high blood pressure
"I'm a 63 year old big guy (315 pounds) with 147/95 blood pressure and otherwise healthy.  This is my first experience with high blood pressure and I am not on any other medication.  I have been taking 20mg lisinopril twice a day for 10 days.  I have experienced the dry cough and blurred vision others have mentioned.  I have taken my blood pressure at home 22 times in 10 days with the following results: High 164/101, Low 137/86, First 140/94, Last 140/88, average 147/95.  My doctor says I should give lisinopril six weeks to work.  I'll try 30 minutes of exercise 5 days a week for the next five weeks and see if there is any improvement."
