@wfsouza First of all, welcome to Connect! Yes, all drugs have side effects, and you are having several of them. I am as surprised as you are that "my cardiologist didn’t take any blood tests and treadmill testing before hand." Especially the blood work. Have you considered seeking another opinion and/or a different cardiologist? Age 76 DOES mean that you deserve the same high level of care as any person at any age.

Metoprolol is a BP medication, as you probably know, I take 50mg each morning (SUCC) to "help my heart work less intensely" ever since a septal myectomy in 2022. I also developed arrythmia after the surgery, fancy medical name for an irregular heart rhythm. May I suggest consulting with a cardiologist whose area of specialty includes rhythm issues and/or electrophysiologist (they specialize in such matters)? Some participants in these Metoprolol discussions found that taking the drug in the morning helped, a question for your doctor.

Here on Connect we encourage people to learn all they can about their conditions. It seems you have researched Metoprolol extensively. Isn't it maddening that a drug that is supposed to be beneficial has an extensive list of side effects, many of which sound horrifyingly worse that the condition the drug is supposed to treat? Let's remember, in trials and follow-up, thousands of people report side effects. If just one person reports a specific side effect, it's added to the list. There may be additional knowledge for you in this article: https://www.mayoclinic.org/drugs-supplements/metoprolol-oral-route/description/drg-20071141. In addition, you may have noted that there are many posts about Metoprolol side effects. What precipitated your visit to a cardiologist who had you wear a heart monitor? Have you looked at or joined the Neuropathy discussion support group here on Connect?
