Typical botox regimen for chronic migraine?

The standard approach for preventing chronic migraine with botulinum toxin A uses a fixed PREEMPT protocol: a total of 155 units given intramuscularly across 31 injection sites around the head and neck, typically every 12 weeks. This pattern was shown in large trials to reduce headache days and was designed to cover the key muscle groups involved in migraine mechanisms, usually delivering about 5 units per site across regions like the frontal, temporal, occipital areas and the neck. The quarterly dosing emerges as the balance between ongoing prophylaxis and safety, making this the established regimen for chronic migraine. The other regimens differ in total dose, site count, or interval and do not reflect the validated PREEMPT protocol for chronic migraine prevention.
