I was just prescribed low dose norvasc for Raynaud's in my feet. It is supposed to cause vasodilation and therefore increase the blood flow by relaxing the vasospasm so my feet will be warmer. Seem to be helping. I am on Cymbalta for several months, but my feet were cold and blue with the slightest drop in temperature.

I know it is not the same problem but the pharmokinetics seem the same.
