Botulinum toxin is a neurotoxin that is primarily used to reduce abnormal contractions of muscles.
Botulinum toxin is effective in treating a variety of neurological conditions including:
Cervical dystonia / spasmodic torticollis
Spasticity following stroke
Hyperhidrosis (excessive sweating)
Prophylaxis of chronic migraine
Please note that treatment for chronic migraine is only administered according to the following criteria:
Headaches present on average 15 or more days per month, 8 of which are migraines.
Treatment will only be continued if a 50% reduction in headache frequency is achieved after 2 treatment cycles of 12 weeks apart.
WHAT SHOULD I BRING TO THE APPOINTMENT AND WHAT CAN I EXPECT?
You will need a referral from your doctor requesting assessment for consideration of Botulinum toxin treatment. Initially you will be reviewed by the neurologist to determine whether Botulinum toxin is appropriate for you. Depending upon the nature of your condition, Botulinum toxin may be administered on the same day, or a follow up appointment may need to be made to administer it on a different day. The initial appointment will take approximately 40 minutes and follow up appointments approximately 20 minutes.
Chronic migraine treatment involves a total of 31 injections over the forehead, temples, back of the head, neck and shoulders. Other treatments involve fewer injections which are dependent upon the condition. Please do not wear makeup (foundation) if you are having treatment for chronic migraine. If you have long hair, please bring a hair tie for treatment of chronic migraine or cervical dystonia.
Botulinum toxin is injected under EMG (electromyography) guidance to target the hyperactive muscle in case of cervical dystonia or post stroke spasticity.
