After trying through dieting and exercise to lower my blood pressure, the doctor finally prescribed 10 mg daily of Norvasc. I saw him every three or four weeks while we worked together trying to lower the numbers.
After the first few weeks when I returned to him for a checkup, my pressure was normal! And I had absolutely no side effects.
After returning again a few weeks later, for the second check up, we realized that the medication was working so well, he lowered the dosage. While going back for checkups every few weeks, he continued lowering the dosage. I am now on a 2.5 mg daily dose, and despite my poor diet and lack of exercise, my blood pressure is normal and staying that way. (PS I do try to watch my diet but am not always successful!)
