Hi , I have been taking Coreg for about 8 years now for my high blood pressure. I had no side effects. Recently I have been given the generic brand Carvedilol.Now I am experiencing ankle swelling and feet swelling and tingling in my fingers. Can it be the Carvedilol I am taking ? I m going to my doctor next week and I want to address this to her. Should I go back to Coreg.
