I have been taking Toprol-XL 50 mg for the past two weeks instead of Altenolol 50 mg. I have been having tight chest, pain in my throat area and lower teeth. I did not have these effects when I was taking Atenolol 50 mg. My cardiologist changed me to Toprol-XL because Atenelol might have triggered by depression again. I had a heart attack 12 years ago. I also take Linisiprol. I cannot walk more than 2 or 3 blocks in a regular pace when I get the side effects listed above. Is this a regular side effect?
