Botox of Little Use for Migraines

Although Botox is licensed for the treatment of chronic migraines in the UK, experts say it is actually of little use for the condition.

Botox, or botulinum toxin, was approved as a treatment because it is thought it may block pain signals as well as being a muscle relaxant. But experts from the Drug And Therapeutics Bulletin said there was "limited evidence" of Botox working for migraine patients.

The Andover Advertiser reports:

“[The experts] questioned the selection of patients used in the clinical trial for the drug, saying the diagnosis of chronic migraine was incorrect as almost two thirds of trial participants overused headache treatments.  Botox leads to worsening of headache symptoms in around one in 10 people, with a similar proportion developing itching, rash, pain, stiffness and muscle spasms, they add.”
