My dad is taking metoprolol 50 mg 2 x a day, and I found out just now that his heart rate his getting low on low 50's & high 50's, & when I look up on his record book it's been going on for a while, is it possible that we could hold it every
time it is below 60. My dad is also taking glimeparide 4 mg 2 x a day, this pill interacts with metoprolol, why did his doctor prescribed this medication?
