About 8 months ago I began to have a little high blood pressure 140/80 and some mild palpitations. I was put on Toprol XL and my nightmare began. I began to have anxiety attacks and my palpitations increased. I was given Xanax to help with the anxiety attacks. I was put on 50 mg. twice a day and I have weaned myself down to 12.5mg daily. I feel much better now but would like to get off of Toprol all together. I have gained weight, and I believe my vision and memory have been affected. Is there any other drug out there that is better to be on? I have never had a heart attack and my echo and stress tests were completely normal. I have read that people with asthma should not take Toprol. I do have allergy shots weekly and have an epi pen. Not sure what to do?? Any advice??
