I have not heard of horizant being used to treat headaches. The main usage I am aware of is to treat Restless Leg Syndrome. I understand Horizant is also used as an anti convulsant, or anti seizure medication, as is topomax, and topomax is used for treating migraine headaches, so I can see where the horizant could be used in the same situation.
