Welcome to justanswer.I am Dr.Sawhney and your complete satisfaction is my goal.
What is the usual range for your heart rate?
Was it 55 before you took labetalol?
If your heart rate remains in the range of 60-75 it should not cause any problem.It may decrease the rate a little further, but that should not be a problem as your body has already adjusted to a lower heart rate.
Cannot really comment on the high blood pressure at waking up though heart rate is usually on the lower side when we wake up.It usually goes up as we resume activity.
Thanks and best of luck.
