In 2010, the FDA approved Botox as a treatment for chronic migraine. Chronic migraine is defined as headaches occurring on 15 or more days each month, at least half of which have migrainous features.
Botox treatments for migraines are typically given once every three months. Treatments span a 15-month period. To perform the treatment, your doctor will inject multiple doses of the medicine in specific points along the bridge of the nose, the temples, the forehead, the back of the head, the neck, and the upper back.
The goal of these injections is to reduce the symptoms caused by a migraine headache. These symptoms include nausea; vomiting; and sensitivity to lights, sounds, and smells.
Most insurance providers now cover the expense of a Botox injection if it is being used to treat chronic migraine.
