Botox helps some people who have chronic migraines at least 15 days per month. People who have long-term migraine headaches, with the attack lasting four hours at a time or longer may use botox to keep the brain from giving off chemicals the body uses to send pain signals.
Typically people get several shots of Botox around their heads and neck once every 12 weeks to dull or prevent migraine headaches.
People usually need 30 to 40 shots in total, and get an equal number on each side of their heads. Some people may have migraine pain in one particular spot, they may need more shots there. The results will be shown in 2 to 3 weeks after first treatment.
