Shortness Of Breath After Walking For A Short Time, Angiogram Normal. Side Effects Of Betaloc?

I shall make an effort to provide you with good professional recommendations specific to your questions.
I understand your concern of shortness of breath is due to betaloc or not.
Yes, dyspnea is indeed one of the reported side effects of metoprolol.
Along with dyspnea, dizziness, fatigue, diarrhea, trouble sleeping and vision problems are mentioned, which of course are not in your case.
So, when any of these occur at the start, reporting is a must.
I am sure your doctor would have discussed this to you, before putting you on. If not, kindly discuss again for a review if you are not able to continue this way.
Your other medications do not have this side effect mentioned and are fine for you at this moment.
Yet again, I duly appreciate your query to me, I do hope that you have found something useful to help you and I shall be glad to answer any further apprehensions.
Sincerely,


As you would like to know more on the interaction of both drugs - Let me explain for you.
Metoprolol is a cardioselective beta blocker drug. Unlike propranolol which is not cardioselective and has a definite interaction with metformin and other antidiabetic drugs metoprolol has less interactions with metformin. Propranolol is not used nowadays because of this and many other reasons.
Now, the risk of dyspnea may be actually and clinically lesser but NOT NIL. That means some still may get dyspnea on it. This is because there is genetic predisposition of metabolizing metoprolol in humans based on an enzyme in the liver. Those who have lower levels of that enzyme may not metabolize this drug as normally should have, enhancing the chances of dyspnea.
Hence, you might be one of those who are having lesser metabolizing ability of metoprolol.
Hope I made it clear.
Regards
