Yesterday the FDA in the United States officially approved Botox for use with chronic migraine patients. This follows a similar approval in Britain for Botox this past summer.
This is a continuation of an up-and-down roller-coaster ride for the controversial treatment. Read more in the New York Times article: Botox Shots Approved for Migraine.
This from the FDA:
To treat chronic migraines, Botox is given approximately every 12 weeks as multiple injections around the head and neck to try to dull future headache symptoms. Botox has not been shown to work for the treatment of migraine headaches that occur 14 days or less per month, or for other forms of headache. It is important that patients discuss with their physician whether Botox is appropriate for them.
The most common adverse reactions reported by patients being treated for chronic migraine were neck pain and headache.
OnabotulinumtoxinA, marketed as Botox and Botox Cosmetic, has a boxed warning that says the effects of the botulinum toxin may spread from the area of injection to other areas of the body, causing symptoms similar to those of botulism. Those symptoms include swallowing and breathing difficulties that can be life-threatening. There has not been a confirmed serious case of spread of toxin effect when Botox has been used at the recommended dose to treat chronic migraine, severe underarm sweating, blepharospasm, or strabismus, or when Botox Cosmetic has been used at the recommended dose to improve frown lines.
Side effects have been rare with Botox treatment, but you are wise to find someone experienced giving Botox injections for migraine, referred by a doctor who knows your medical history.
