What is the Dosage of Botox for Use to Treat Migraines?

Please keep in mind that not every one responds to BOTOX for migraines.  The dose is adjusted to your response so the dose is based on what you need recognizing that increasing dose is associated with increasing side effects.

Since Botox works to block the neuromuscular receptors, preventing a muscle from contracting, it works well in many patients to alleviate migraines.  Most migraines originate from involuntary muscle contracting or having some sort of spasm around particluar nerves.  This is why most patients with severe migraines always start at the same area and then radiate out to encompass the entire head.  If a patient can pinpoint the area, then Botox into the underlying muscle can help take the spasm away and alleviate the pressure on the nerve.  There is no defined dosage, since it really varies from patient to patient.  It also does not work for everyone, but in a majority of patients, they get good migraine relief for 3-4 months.  I hope this helps.
