If you have this diagnosis, it would be dangerous not to be on a beta blocker which is what Coreg is.
Coreg is really
the best beta blocker and blocks
the most receptors. Now that you are on
Coreg, you should try not to worry too much. Just do not miss a dose or go off of it suddenly. Follow-up with your doctor. If you experience flutter with the Coreg, make sure to see your doctor.
