I have been on Corgard many years ago and it cause many problems with side effects. I started throwing Premature Ventricular Contractions. My cardiologist switched me to Tenormin ( Aetenol) which had eleimanted all the side effect except one. A typical problem with PD is Hypotension. Sometimes my BP gets too low and I get dizzy. I would not go back to Corgrad!! Ciao David [log in to unmask]
