I have a fib and am trying to get my bp in check. i am taking atenolol an xeroltrol but bp is still all over?

See your physician: Although some drugs are used for both, hypertension has to be dealt with as a separate issue. Many people require two or three drugs (having different mechanisms of action) to control their blood pressure. You need to see your physician. Usually, drugs to control blood pressure are added one at a time with the goal of finding a long-term regimen

Dosing prob: I think you meant "Xarelto" which is a blood thinner and should have no effect on BP. You must take atenolol regularly; if you miss a dose, you can get a rebound effect until the dosing is resumed to steady state. Also, you could be under-dosed; the only way to know is to check your heart rate (which should be around 60 BPM if dosed correctly) when your BP is "all over"
