This drug (procardia; generic is called nifedipine) has very few side effects for me so far. Of course, I'm on a much lower dose than would be required for high blood pressure (what the drug is typically used for). It does cause some dizziness, but now that seems to be subsiding. It can also cause water retention. Oh, I've also noticed some flushing shortly after I take it, but I think the extra color looks very attractive on me :)
I sure hope no one has raynaud's bad enough to take meds, but if you do, I've had great success with this one.
