WASHINGTON — Botox, the botulism-based drug that has wiped wrinkles from the faces of millions, may be approved for another use: stopping headaches.
Drug maker Allergan Inc. said Thursday that it had new evidence that its injectable drug could help relieve migraine headaches. Based on preliminary results from two company-funded studies, Allergan said it would ask the Food and Drug Administration to approve Botox for chronic migraine next year.
