Metoprolol - Short bursts of shortness of breath

Sounds much like me, except that when I experience tacchycardia (for no apparent reason, rarely) I do take 12.5 mcg and it helps.

(Trying 25 mcg my first time, I developed the same bp, BPM and extreme shortness of breath as you describe. Nearly passed out. Thereafter, I was told by my cardiologist that I could take a half dose PRN. Mostly I avoid it like the plague.)

Sounds like the metoprolol is very effective PRN for tachycardias but is overkill for non-tachycardiac rhythms. It was incorrectly prescribed for PVC suppression in my case but beta blockers are poor PVC suppressors. The heart rate reduction exacerbates the symptoms of the already reduced numbers of effective beats from the PVCs.
