HOW DOES BOTULINUM TOXIN A WORK?
Botulinum Toxin A, in addition to its well-known effect on the motor endplate, also acts at the level of sensory afferent nerve endings (C fibres) inhibiting the release of local inflammatory substances.
WHO ARE THE CANDIDATES FOR TREATMENT WITH BOTULINUM TOXIN A?
All patients with chronic migraine are eligible for this treatment. Chronic migraine is currently defined as episodes of headache that occur on 15 or more days in a month, for more than 3 months, with characteristics of migraine, on at least 8 of those days. Its prevalence is 1 to 2% in the population, and it is estimated that one third of patients are not adequately treated.
HOW IS THE TREATMENT WITH BOTULINUM TOXIN CARRIED OUT?
The application of Botulinum Toxin A is carried out according to a pre-established and approved protocol according to previously performed clinical trials. The protocol involves the injection of 31 predefined points distributed between the cephalic and cervical regions according to the PREEMPT study. A very fine and very small needle is used which minimizes the painful effects of the bites. After each bite, a brief local burning may occur. The procedure is usually very well tolerated by patients who immediately resume their usual activities. This procedure should only be performed in centres specialised in the protocol and it implies clinical correlation and surveillance in the consultation of Headaches.
