I see that you too are on carvedilol for vasospasms. I have them as well, and I've been on various betas. My last was metoprolol 6.25mg tid. Tiny dose, but it didn't lower b/p that much during day but has plummeted h/r to 55 or less. Using it with nitro patch. Today I'm retrialing carv.3.125 bid. any info would be appreciated on your feelings on this drug.
