I have been on Atenolol for many years. Started out at 50mg. Several years ago my doctor said I could go off it as I was on Norvasc and Diovan. Based on a 24 BP monitor, it was discerned I did not need the Atenolol. I was able to cut my dose to 25mg. but cannot get off it. I become irritable, jittery and have a short fuse. Recently, became a vegan and my BP has dropped so I tried to d/c the atenolol once again. Will I ever be able to get off this med. my BP is 101/60 just on 5 mg. of Norvasc.
