I was diagnosed with idiopathic dilated cardiomyopathy 2 years ago. I took 25 mg of coreg twice a day and my ef went from 15% to 63% in 1&1/2 years. My bp and heart rate were very low and I spent about 1/2 of each day laying down because of weakness and dizziness. My doctors took me off coreg for 3 days to see if it was side effects from the meds. I experienced increased energy and a clear mind for the first time in 2 years. Now I am taking 6.5 mg in the a.m. and 12.5 mg at bedtime. I am tolerating this pretty well, my heart rate is in the 50's & low 60's. I think I am at least partially beta blocked however, I am wondering what the minimum effective dosage is for coreg? I sure don't want to lose my gains. The heart transplant team doctors tell me I will most likely go back to an ef similar to what I started with if I go completely off coreg. Is that what you are finding at the Cleveland Clinic? Thank you, Jan.

The answer to your question is the BIG UNKNOWN. We do know that people with your bad EF that improves on coreg tend to worsen off the drug, BUT as with all things in medicine, NOTHING IS 100%, i.e. it is not a guarantee that you will worsen on a smaller dosage, even off the coreg! Be wise however, do not stop your close follow-up, work with your doctors, follow the course of your EF and if it worsens be willing to increase the coreg dose again (makes common sense though does it not?)
