So, if you do decrease your Toprol XL dose by 50%, record your BP and heart rate at least 4 or 5 times a day
, until it becomes stable again. You
would logically think that reducing a
dose of BB would cause your BP and HR to increase, BUT it can have the opposite affect. I personally have increased my dose of BB by 50%, and my BP and HR went high and was chaotic for awhile, until the autonomic nervous system can become stable again.
