Is it safe to take verapamil and metoprolol together for severe pvcs??

In general, yes: Medications like metoprolol and verapamil are good first-line treatments for symptomatic PVCs. They both work to slow down the conduction of the heart and thus the heart rate, and while this can help with severe PVCs, these medications can sometimes cause the heart rate to go too slow, especially when used together. If this happens, you may have symptoms like lightheadedness or passing out.
