OnabotulinumtoxinA (Botox) for migraine
Periodic injections used specifically for chronic migraine prevention, distinct from cosmetic use, offered strictly within its studied indication.
What it is & how it works
Periodic injections of botulinum toxin type A used specifically for chronic migraine prevention, distinct from cosmetic use, thought to work by blocking the release of pain-signalling neurotransmitters around peripheral nerve endings.
How it's done
Typically administered using a fixed-site, fixed-dose injection protocol (commonly around 155 units divided across roughly 31 sites across the forehead, temples, back of the head, neck, and shoulders), performed in-clinic by a physician, and repeated approximately every 12 weeks for patients who respond.
Conditions it treats
Why Brain Bridge
Offered strictly within its studied chronic-migraine indication, consistent with Brain Bridge's evidence-bounded positioning rather than as an off-label or cosmetic-adjacent offering here.
Evidence & safety
Supported by controlled trial evidence for the chronic migraine indication specifically.
Related questions
Both use the same active ingredient (onabotulinumtoxinA) but are different approved products used at different doses: chronic migraine treatment follows a fixed protocol of roughly 155 units across about 31 sites, considerably more than typical cosmetic dosing, and is approved specifically for the chronic migraine indication.
The most common is neck pain or stiffness in the days after injection. Less commonly, temporary changes in forehead appearance or mild flu-like symptoms can occur; rare but serious effects such as difficulty swallowing or breathing have been reported and should be discussed with your physician beforehand.
