Botox May Help Prevent Migraines

A U.S. drug maker said two Phase III clinical trials show Botox injections can help prevent chronic migraines.

Allergan Inc. said it hopes to file an application with the U.S. Food and Drug Administration for the use of Botox in patients with chronic migraines by the middle of next year after full data results are presented.

The Wall Street Journal said some researchers were surprised by the findings. The American Academy of Neurology earlier this year advised physicians that, based on information available at the time, Botox injections weren't effective in the treatment of migraine or chronic tension headaches, the newspaper said.
