The FDA has approved 4 different types of botulinum toxin for various therapeutic indications. The oldest, the most popular and the only one approved for the prevention of chronic migraines is onabotulinumtoxinA, or Botox. I’ve been injecting Botox for headaches for over 25 years and have written many blog posts and long articles about it. You can read about Botox for kids with chronic migraines in this post.
A new development in the botulinum toxin field is a long-acting form of botulinum toxin, daxibotulinumtoxinA , which may become available in a couple of years. Its effect on muscles and nerve endings appears to last 6, instead of the 3 months seen with Botox.
