An update to my recent postings - on Saturday 11/24/07 - I began the step down of Toprol and the transition to Diovan 80 mg -- it is DIFFICULT. My B/P at times has skyrocketed, I have gotten headaches, and intense chest pain. The finally straw was when my pulse went over 200 and woke me up @ 5:30am - my husband rushed me to the E.R. and the Dr. confirmed that it was side effects from coming off the Toprol -- he said that I should have been given a long term acting anti-anxiety medicine to help me "not feel the side effects" as much. They tested my heart, etc. and all tests came back great - so he prescribed me some Valium to help get me over the worse of the re-bound symptoms and said that I should start to feel some relief in a few days - but to keep on it because getting off this medication (Toprol) - is the best thing for getting my asthma back under control.
