Botox for migraines is the therapeutic use of botulinum toxin in patients with chronic migraine, according to medically defined protocols. The treatment can reduce the frequency, intensity and duration of migraines and, for many patients, may also reduce the need for pain medication. It is intended for people with frequent, long-lasting headaches that significantly affect quality of life. The treatment plan is individualized, and the procedure is usually repeated every 12 weeks, or approximately every 3 months.
