How long does Lopressor stay in system ?

I remember changing BP medicine and my Doctor told me it would take 48-72hrs to rid my system of atacand. It typically takes 2-3 days for the active medicine to leave your system and then it should be ok to try a new medication. In the past 8 years I have changed medications three times and really did not suffer any withdrawl but it was always difficult adjusting to new medication for me.

Has this been your regular blood pressure medicine? If so you should really ask your doctor as when changing from one BP medicine to another, I went through withdrawls. Thank goodness I was at work when this happened and my doctor was across the street. I spent a few hours in his office sweating and then shivering.
Please be careful
