BTX/A is an effective treatment for chronic migraine — defined as 15 or more migraine days per month, each lasting at least 4 hours. The treatment follows the PREEMPT protocol, involving 31 small injections across 7 specific muscle areas of the head and neck.

🕒 Onset:
– Initial relief: 4 – 10 days

Treatment is offered to patients with an established diagnosis of chronic migraine by their GP or neurologist. This service does not replace specialist neurological care.
