If your blood pressure is high and is then put to normal, your heart will not have to work so hard to push
blood around your system. However, I had very high
blood pressure for years and was also put on Ramapril. My blood pressure was higher than yours and I was on 5mg daily which seemed to be too much, it was reduced to 2.5mg. The only way to establish if the dosage is incorrect is to get your blood pressure measured.
