My health care provider has prescribed clonidine 0.1 mg bid, and i'm already taking norvasc and cozaar. I have been taking it for two days. I have a long history of bradycardia, and have a heart rate in the low to mid 40's since taking the clondidine. I am also very tired and drowsy since taking it. Is this something I should be concerned about or will it get better? I was also instructed to increase the dose after a week if my b/p does not come down to a normal level. Your opinions on this?
