SILVER SPRING, Md. A popular beauty treatment has won approval as a medical treatment as well.

The Food and Drug Administration announced Friday the approval of Allergan’s Botox (onabotulinumtoxinA) for preventing headaches in adult patients with chronic migraine.

“Chronic migraine is one of the most disabling forms of headache,” FDA division of neurology products director Russell Katz said. “Patients with chronic migraine experience a headache more than 14 days of the month. This condition can greatly affect family, work and social life, so it’s important to have a variety of effective treatments available.”
