Allergan Inc. (AGN) (AGN)’s wrinkle treatment Botox, approved in the U.S. for preventing chronic migraines, provides only modest relief for patients with the headaches, an analysis of previous studies showed.

The study, published today in the Journal of the American Medical Association, found that Botox had no benefit for those with episodic migraines that occur less than 15 times a month, or chronic tension headaches that occur more than 15 times a month. The analysis also showed that Botox reduced chronic migraines and daily headaches by only about two per month.
