Coreg, or carvidilol which is the
generic replacement, is a very powerful
drug. It is difficult to take, that is why you are being given a very small dose twice a day. It makes you very tired, and slows your metabolism. However, your body will get used to it, and the drug has properties that allow your heart to heal the heart. Once your body is used to the drug, often it is double, then doubled again, perhaps a third time. I took 50mg a day for a number of years.
