Although there are no approved medications for Raynaud’s, doctors sometimes prescribe drugs used for other conditions, such as vasodilators, which improve circulation by opening blood vessels.

For instance, the immune system releases a molecule after a vaccination known as a vasodilator, which inflates local blood vessels and can cause swelling and redness near the injection site.

Like CGRP, it is a vasodilator found in the trigeminal nerve.

The authors’ findings therefore suggested that another vasodilator was being formed.

Improve your sleep by regulating your body temperature and aid blood flow, thanks to the vasodilator effect that expands your blood vessels.
