Most often botox is used as a prophylaxis for chronic migraine sufferers who have failed to respond to other forms of medications and treatments. For patients who still experience more than 15 headache days per month despite therapy, each lasting at least 4 hours, and do not have any component of medication overuse headaches, botox therapy has been proven a very effective treatment in these patients. Injections are covered by insurance and are given on a 12 week schedule. 31 different sites are injected at each session for a total of 155units of Botox. Patients need to have this done at least two sessions in order to determine if Botox will work to control their symptoms.
After assessing the amount of headache reduction following the first two treatments, you and your doctor can determine if continuing the therapy is right for you.
