Chronic migraine is one of the most disabling forms of headache, “Patients with chronic migraine experience a headache more than 14 days of the month. This condition can greatly affect family, work, and social life, so it is important to have a variety of effective treatment options available.

The procedure can be done in the office, with little discomfort to the patient, and is completed within 15-20 minutes.

What is botulinum toxin? Botulinum toxin is produced by the bacterium, Clostridium botulinum. Seven different subtypes of botulinum toxin (A-G) are known. A highly dilute preparation of botulinum toxin type A Botolinum toxin injection was introduced in clinical practice in the 1970s and 1980s to treat squint and blepharospasm. Since then it has found uses in other areas of neurology including hemifacial spasm, writer’s cramp, cervical dystonia, post-stroke spasticity.

Botulinum toxin and headache In the mid-1990s a number of people reported improvement in headaches in patients receiving botulinum toxin for other reasons. Well-conducted clinical trials of botulinum toxin in various types of headache followed. Detailed analysis of the results suggested, however, that there might be a subgroup of patients with chronic migraines who could benefit, and further trials were undertaken.

Botolinum toxin injection in chronic migraine: the PREEMPT trials Two Phase 3 Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) trials recruited 1384 patients with chronic migraine, and randomized them to treatment with Botolinum toxin injection or placebo. These patients were suffering on average 20 days of headache each month, of which 18 were moderate or severe. Those randomized to Botolinum toxin injection received fixed-site, fixed-dose injections every 12 weeks over 56 weeks. These injections covered seven specific areas of the head and neck, with a total dose of between 155-195 units. At six months, after two cycles of treatment, those treated with Botolinum toxin injection had on average eight fewer days of headache each month. After 12 months, 70% of those treated had ≤50% the number of headaches that they had done originally.

How does botulinum toxin work in chronic migraines? Unlike many of the other conditions in which it is used, it is not thought to work by relaxing overactive muscles. Botulinum toxin has been shown to reduce pain in a number of disease states, including cervical dystonia, neuropathic pain, lower back pain, spasticity, myofascial pain, and bladder pain. Botulinum toxin is believed to inhibit the release of peripheral nociceptive neurotransmitters, which may then have a knock-on effect on the central pain processing systems that generate migraine headaches.
