My Doctor prescribed 5mg of Norvasc for me a 48 year old male. I was taking atacand for 3 years and noticed it was causing me to feel tired and not working as well. I noticed swelling in my ankles and legs within a week of taking Norvasc and was told this was a side effect. I continued to excercise and do alot of walking but the problem became worse and I had to stop taking the medication. I firmly believe that the medication caused the swelling and discomfort .What would be a better substitute for the medication.
