Hi,
I'm sorry to hear you've been having some worsened health while on
Metoprolol. Metoprolol does have some of the side effects that you have mentioned, such as trouble breathing and fatigue. I am guessing you take it for atrial
fibrillation.
I would recommend you don't stop taking the Metoprolol again, but discuss with your doctor about switching it to another medication for controlling your
heart rate, like
Diltiazem, or, if that isn't an option, Digoxin. However, your doctor may have already considered these options and decided against them based on your particular medical history.
It is also possible that your
shortness of breath and fatigue is from your underlying heart condition, though if your symptoms improved when you stopped the Metoprolol, I would suspect the Metoprolol is the cause too. In summary, I recommend you discuss switching to Diltiazem or Digoxin and see what he or she says.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Aaron Branch, General & Family Physician
