Botox is the common name of the botulinum toxin, a purified protein from the Clostridium botulinum bacterium. People often consider Botox as a cosmetic procedure to reduce fine lines and wrinkles on the face, but Botox for chronic migraines is an FDA-approved use of medication.
Botox works against migraines by targeting the muscles and nerves in the neck and head that trigger them. The protein blocks nerve signals to those muscles.
Unfortunately, the treatment doesn’t work on all migraines. About 1% of Americans have chronic migraines that affect them more than 15 days a month.
