Understanding Chronic Migraines
Chronic migraine is characterised by frequent headaches. To meet the definition, you must experience headaches on 15 or more days per month for longer than 3 months, with at least 8 of those headache days showing migraine features. Migraine symptoms often include –
- Severe, throbbing pain, frequently on one side of the head
- Nausea or vomiting
- Increased sensitivity to light and sound
Neurotoxin for Chronic Migraine Prevention
Neurotoxin injections are an approved preventative treatment for adults who have been diagnosed with chronic migraine.
Mechanism – It is believed that the neurotoxin interrupts pain signalling pathways involved in the development of a migraine headache.
Treatment Protocol – The treatment involves injecting defined neurotoxin units into specific, shallow muscles following a set pattern (based on the PREEMPT study) across the forehead, temples, back of the head, neck, and upper back/shoulders.
Frequency – To maintain its preventative effect, treatment is typically administered by Susie every 12 weeks.
Goal – The aim is to reduce the number of headache days you experience each month and lessen the severity of migraines. For some patients, 2 or 3 treatment cycles may be needed to notice a significant reduction.
NICE* recommends botulinum toxin type A for adults with chronic migraine who have failed to respond to at least three different oral preventive treatments and whose medication overuse has been appropriately managed.

Your Migraine Treatment Consultation
During your consultation appointment, Susie will carefully review your migraine history. This includes the pattern and frequency of your headaches and any previous treatments attempted.
Susie will assess your suitability for this preventative neurotoxin treatment based on established clinical guidelines. She will explain the specific injection procedure, potential benefits, possible side effects (including common but usually mild ones like neck pain, and less common ones like temporary eyelid drooping), and the treatment cost. This is your opportunity to ask questions and ensure you fully understand your proposed plan.
The Treatment Procedure
The neurotoxin treatment for chronic migraine prevention is administered by Susie according to the specific PREEMPT protocol*.
Using a very fine needle, Susie will inject small amounts of the neurotoxin solution into the predetermined muscle sites around your head and neck. The appointment for the injections usually takes approximately 15 to 20 minutes. Most patients tolerate the procedure well, reporting only mild, temporary discomfort during the injections.
