No difference at all. What they did was got FDA approval to market it for migraine use. SO they repackage it under a new name, and charge a buck extra until people catch on.
(The caffeine is a vasoconstrictor...shrinks the blood vessels in your head, essentially. Pretty effective for headaches - except that caffeine is a migraine trigger for some.)
