A review of all available data on treating migraines and tension-type headaches with Botox indicates it is no better than a placebo, according to a US News & World Report article. The findings are included in guidelines for using Botox published in today’s issue of the journal Neurology.
[B]otulinum toxin has become an effective treatment for numerous movement disorders associated with excessive muscle contraction.
The new guidelines approve its use for treating cervical dystonia, a condition of involuntary head tilt or neck movement; involuntary facial contractions, involuntary eye closure, focal limb dystonias (such as writer’s cramp), essential tremor and some spastic bladder disorders. The drug is injected directly into affected muscles.
The finding that botulinum toxin probably does not help relieve migraine or chronic tension headaches surprised the researchers.
“Based on currently available data, botulinum toxin injections should not be offered to patients with episodic migraine and chronic tension-type headaches,” pain guidelines author Dr. Markus Naumann, head of the Department of Neurology at Augsburg Hospital in Germany, said in a prepared statement. “It is no better than placebo injections for these types of headache.”
I haven’t even found the abstract yet. I’ll let you know as soon as I learn more about this surprising report. If you know anything about it, please leave a comment below.
