FDA approves Botox for migraine headaches

WASHINGTON (AP) - Federal health officials have approved the wrinkle-smoothing injection Botox for migraine headaches. It gives drugmaker Allergan clearance to begin marketing its drug to patients with a serious history of the condition.

The Food and Drug Administration approved the drug for patients who experience 15 or more days of migraine headaches per month. Allergan says roughly 3.2 million people in the U.S. have chronic migraines.

For the new use, doctors are directed to inject patients in the neck or head every 12 weeks to dull future headaches. Doctors currently use a wide variety of medications to treat migraines, ranging from over-the-counter painkillers to prescription narcotics.

Many patients also respond to changes in diet or lifestyle. The FDA approved the new use based on two company studies.
