What to Expect from BOTOX® Treatment for Chronic Migraine
How BOTOX® for Chronic Migraine Is Administered
BOTOX® is a Health Canada–approved treatment for chronic migraine relief in adults who experience 15 or more headache days per month. At Chinook Medical Centre, we provide in-clinic BOTOX® treatments designed to help prevent migraines before they start.
Each session typically lasts 10 to 15 minutes and involves 31 small injections across 7 muscle areas in the head and neck — including the forehead, temples, scalp, upper neck, shoulders, and notably the trapezius muscles. These injections use a fine needle, and most patients describe the sensation as light pinches.
The standard dose is 155 units, but in many cases, healthcare providers optimize dosing up to 195 units by administering additional injections based on the PREEMPT protocol to target predominant pain areas. Treatments are administered every 12 weeks, and patients can return to normal activities shortly after.
When Will I See Results from BOTOX® Migraine Treatment?
Most patients begin treatment with at least 3 cycles spaced 12 weeks apart to fully evaluate BOTOX® efficacy. Many individuals notice initial relief within 4 to 6 weeks after the first treatment, with full therapeutic benefits typically apparent by week 24, after the second or third treatment.
Clinical studies show BOTOX® reduces headache days by 8 to 9 days per month on average for chronic migraine sufferers. In addition to fewer migraine attacks, patients often experience less severe pain, reduced need for acute medications, better response to other treatments, and improved tolerance to migraine triggers.
At Chinook Medical Centre, we personalize your treatment plan to suit your migraine history, symptoms, and goals — ensuring compassionate care throughout.
