[|Human|] I took 500 mg Atenelol per day (300 in am and 200 pm) At the moment there is a shortage of Atenelol and my dr. switched me to Metoprolol 200 in am and 200 in pm. My heart rate has decrease in the last couple of days from normal 72 to high 90 s. Can this be related to the switch?
[|AI|]  Hi Greetings from Chat Doctor As far as Atenolol and Metoprolol are concerned there is not much difference. As Metoprolol is started fresh, its blood level will rise day by day. Maximum effect will be there after 10 days. So just relax and wait for a few days more. What is level of BP? If you have any further query then you can come back to Chat Doctor. I will definitely help you and guide you appropriately. Take Care Chat Doctor.
