I was prescribed i for the anxiety i get from the PACs. My cardiologist gave me metoprolol
for the PACs. The xanax doesnt do anything to help the PACs. To be honest, the metoprolol I take doesnt seem to be working for me either because i still get the same amout od skippd beats as i did before. KAREN.... I feel your pain, I dont know if i could ignore or try to live with the PACs. the beta blocker doesnt seem to be doing anything, the xanax dosnt do anything but make me a little tired.
