Botox may cut the number of migraine headaches in some patients.

That's what researchers told members of the American Headache Society at their annual meeting in Philadelphia.

Botox is famous for smoothing out wrinkles. The new study shows that its effects may be more than skin deep.

The study looked at a specific group of migraine patients -- those with frequent attacks who normally would require daily preventative medications.

There are about 6 million people in the U.S. with that problem, or about 2% of U.S. migraine patients, says researcher David Dodick, MD.

Dodick works at the Mayo Clinic in Scottsdale, Ariz. He spoke about the study in a media teleconference.

Botox Study

Dodick's team studied 288 migraine sufferers. On average, they had headaches on 13.5 days of the month. They were about 42 years old; most were women.

Participants weren't taking any medications to prevent those migraines from occurring, says Dodick.

Some patients got three treatments of Botox, spread over 11 months. The others got placebo injections.
