Migraines Treatment

What is Chronic Migraine?

Chronic migraine is defined as headaches on 15 or more days per month, with at least 8 days having migraine features, for more than 3 months. This condition impacts quality of life, work productivity, and daily functioning.

The Science Behind Botox for Migraine

Botox works by blocking the release of certain neurotransmitters involved in pain transmission. Specifically, it:

Inhibits the release of pain-related and neurotransmitters (such as substance P, CGRP, and glutamate)

Prevents peripheral sensitisation of pain nerve endings

the activation of central pain processing pathways

Relaxes muscles that may contribute to headache components

The standardised injection technique for Botox in migraine treatment is based on the PREEMPT (Phase III Research Evaluating Migraine Prophylaxis Therapy) clinical trials. This protocol established the specific injection sites, dosing, and administration technique that demonstrated efficacy in treating chronic migraine.

Fixed-site, fixed-dose approach: The protocol specifies 31 mandatory injection sites across 7 key head and neck muscle areas, with a total of 155 units of Botox

Follow-the-pain strategy: Up to 40 additional units may be administered in areas where patients experience the most pain, allowing for treatment

Bilateral injections: Injections are administered on both sides of the head and neck

Shallow intramuscular technique: Precise injection depth and angle to target specific muscle groups

Evidence-based effectiveness: This approach was validated through large-scale clinical trials showing significant reduction in headache days

The PREEMPT targets these muscle groups:

Frontalis: Forehead muscles (10 units divided between both sides)

Corrugator: Muscles between the eyebrows (10 units divided between both sides)

Procerus: Bridge of the nose (5 units)

Occipitalis: Back of the head (30 units divided between both sides)

Temporalis: Temple area (40 units divided between both sides)

Trapezius: Upper back/shoulder muscles (30 units divided between both sides)

Cervical paraspinal: Neck muscles (20 units between both sides)

This systematic approach ensures consistent treatment delivery and replicates the conditions under which Botox was proven effective in clinical trials.

FAQs

Proven efficacy: Strong clinical supporting its effectiveness in reducing migraine frequency and severity

Reduced medication burden: May the need for acute migraine medications and reduce the risk of medication overuse headache

Favourable safety profile: Generally well-tolerated with minimal systemic side effects compared to oral preventive medications

Convenient dosing: treatment only four times per year

Quality of life improvements: Significant improvements in disability, work productivity, and overall well-being

Non-systemic treatment: Works locally without requiring daily oral medication

No drug interactions: Does not interact with most other medications

Time to effect: May take 2-3 treatment cycles (6-9 months) to achieve results

Ongoing commitment: Requires regular appointments every 12 weeks

Not effective for everyone: Approximately 60-70% of patients respond to treatment

Temporary effects: Benefits wear off over time, requiring continued treatment

Common Side Effects

Most side effects are mild and temporary:

Neck pain or stiffness (most common)

Headache (may occur initially before improvement)

Muscle in the neck or shoulders

Drooping eyelid (ptosis) – rare and temporary

Injection site pain, bruising, or swelling

Flu-like symptoms

Rare but Serious Side Effects

Though uncommon, patients should be aware of:

Difficulty swallowing or breathing

Speech problems

Severe muscle weakness

Allergic reactions

The NHS recognises Botox as an evidence-based treatment for chronic migraine, supported by NICE guidance (TA260) from 2012. Access is restricted to patients who meet specific criteria: chronic migraine diagnosis (15+ headache days per month), of at least three oral preventive medications, resolution of any medication overuse, and specialist referral. Treatment is provided free when approved, typically with a 6-month trial period. However, availability varies significantly by region and CCG, with potential waiting times for assessment and treatment.

While the NHS recognises Botox as for chronic migraine, access can be limited by strict eligibility criteria, regional variations, and lengthy waiting times. At Karwal Aesthetics, we are a private healthcare provider and do not work with the NHS. We offer migraine at out London, Mayfair clinic.

Clinical data shows:

Response rate: Approximately 60-70% of patients experience a reduction in headache days

Average reduction: 8-9 fewer headache days per month

Improvement timeline: Gradual improvement over the first 2-3 treatment cycles

Sustained benefits: Many patients maintain improvement with continued treatment over several years

Acute medication use: Significant reductions in the need for pain-relieving medications

Consultation: A thorough assessment is performed to confirm the diagnosis of chronic migraine and to rule out other causes of headache.

Preparation: The skin is cleansed. No anaesthetic is usually required as the injections are quick and use a very fine needle.

Injection Sites: Botox is at multiple sites across the head and neck, following a standardised protocol known as the PREEMPT (Phase III Research Evaluating Migraine Prophylaxis Therapy) protocol.

Typical areas include the forehead, temples, back of the head (occipital region), neck, and shoulders.

In total, around 31–39 injections are given in one session.

Procedure Time: The treatment takes about 15–20 minutes.

Aftercare: Patients can return to normal activities immediately, though it’s best to avoid strenuous exercise for 24 hours.

Botox is injected into seven key muscle areas around the head and neck, including:

Forehead (frontalis muscle)

Temples (temporalis muscle)

Back of the head (occipitalis muscle)

Neck (cervical paraspinal and muscles)

Above the ears (temporalis)

Bridge of the nose (procerus)

Upper shoulders (trapezius)

This multi-site approach targets the nerves and muscles most commonly involved in migraine attacks.

The ideal candidate for Botox treatment typically:

Has chronic migraine: Experiences headaches on 15 or more days per month, with at least 8 days having migraine features

Has not responded adequately to other preventive treatments: Has tried at least 2-3 oral preventive without sufficient benefit

Experiences significant disability: Migraine substantially impacts work, school, or daily activities

Is 18 years or older: Botox for chronic migraine is approved for adult patients

Can commit to regular treatment: Willing to attend appointments every 12 weeks

Has realistic expectations: Understands that results may take several months to manifest

Botulinum toxin type A, commonly known as Botox, has emerged as an effective preventive treatment for chronic migraine. Initially approved by the FDA in 2010 for this indication, Botox represents a significant advancement in migraine management for patients who experience frequent and .

The NHS recognises Botox as an evidence-based treatment for chronic migraine, supported by NICE guidance (TA260) from 2012. This dual recognition from both American and British regulatory authorities underscores the robust clinical evidence supporting Botox as a legitimate option for chronic migraine sufferers.
