Migraines are often described casually as “bad headaches”, but chronic migraine is a defined medical condition with a real impact on work, family life, and day-to-day functioning. The confusing part is that Botox sits in two worlds at once: many people know it as an aesthetic injectable, yet in migraine care, it’s used in a structured, clinical way for specific patients. That overlap can make it hard to tell what’s evidence-based, what’s appropriate for your situation, and what questions to ask before you commit time, money, or hope. 

A careful understanding matters because Botox for migraine is not a casual add-on treatment. It involves repeat appointments at set intervals, and it should be delivered by a medically qualified practitioner with specific experience in migraine protocols, who is accountable to a UK regulator such as the GMC, NMC, or GDC. Side effects are uncommon, but they can happen, and it’s important to know what is considered normal, what is not, and when to seek help.

In the sections below, you’ll learn who may be eligible (including when the NHS might fund treatment), what a typical treatment course looks like, realistic costs in private settings, and the key safety points to check before booking a consultation.

What Is a Chronic Migraine and What Causes Them?

A chronic migraine is characterised by recurring headaches that cause mild to severe pain on one side of the head. These chronic migraine attacks can last hours up to three days and are often accompanied by nausea and vomiting.

Unfortunately, chronic migraine and episodic migraine symptoms are often accompanied by sensitivity to light and sound as well. Chronic migraine pain is typically throbbing in nature, but it can also be stabbing or dull aches.

While their exact cause is unknown, chronic migraines are thought to be associated with temporary changes in nerves, blood vessels and chemicals in the brain. Migraines can be triggered by stress, tiredness, certain foods or coming on your period.

How Can Botox Help Chronic Migraines?

Botox can be used as a chronic migraine treatment. Botox is a brand of botulinum toxin – a neurotoxin which interferes with the transmission of nerve signals throughout your body.

Botulinum toxin is thought to help treat migraines by blocking the chemicals that carry pain signals from within your brain when injected around the nerve endings where pain transmission takes place. This can cut down the symptoms completely or partially reduce the number of migraine attacks.

Botox is approved for use on the NHS for treating frequent migraines. These are defined as more than 15 headaches a month, with at least eight showing symptoms of a chronic migraine. Botox has not been found to be effective for tension or cluster headaches.

What Does Migraine Treatment With Botox Involve?

Botulinum toxin is injected into seven muscles around the top of the forehead, above the ears and into the neck via a small needle. You will have around 31 small Botox injections. The areas can be numbed beforehand.

You may notice some redness and/or swelling around the injection points, which will settle after a few hours.

Repeated Botox injections for migraine treatment are needed every three months, usually until your chronic migraines change to episodic migraines for 12 weeks in a row.

How Much Does It Cost to Treat Migraines With Botox?

You may qualify for free treatment for chronic migraine on the NHS - speak to your GP for an assessment. If NHS treatment using Botox for migraine isn't an option for you, private treatment cost varies, with an average cost of around £500.

Always see a practitioner with specific experience in using botulinum toxin for migraines.

Don't be swayed by price!

Are There Side Effects to Treating Migraines With Botox?

Side effects of using Botox for migraines and other brands of botulinum toxin are rare, but can include:

  • Exacerbation or increase in headaches/migraines

  • Neck muscle stiffness or pain

  • Swelling

  • Allergic reaction

  • Droopy eyelids

  • Dry eyes or mouth

  • Facial paralysis

The most dangerous complications are double vision and difficulty breathing, but these are thankfully extremely rare.#

If you experience any side effects or complications, contact your practitioner immediately.

Who Should You Trust to Treat Your Migraines With Botox?

Using Botox for migraine is a medical treatment, so it's really important you see a medically-qualified practitioner with specific training in this area.

They should have undergone training in anatomy and physiology, as well as being accountable to a regulatory body such as the General Medical Council (GMC), Nursing and Midwifery Council (NMC), or General Dental Council (GDC).

They should also be able to advise you of the risks of injectable migraine treatment and be confident in handling complications if they arise.
