What is BOTOX for Migraines?
Botox is not recommended for patients who experience fewer than 15 headache days a month. It is only FDA-approved for chronic migraines, which means headache on 15 or more days a month.
Botox is a form of botulinum toxin, a neurotoxin produced by the bacteria that causes botulism. When the Botox botulinum toxin is purified and used in tiny doses in specific areas, it temporarily reduces muscle contractions for approximately 3 months.
It’s important to note that before your insurance company will approve Botox as a treatment for your chronic migraine, typically you must have tried and failed to respond to two other preventative treatments, such as anti-seizure medications, antidepressants, or blood pressure medications that are generally used in preventing migraines.
Why are BOTOX injections performed for Migraines?
Botox enters the nerve endings around where it is injected and blocks the release of chemicals involved in pain transmission. This prevents the activation of pain networks in the brain.
Botox prevents migraine headaches before they start, but takes time to work. Each treatment lasts for approximately 10 – 12 weeks. Generally, patients will have a noticeable reduction in the number of headache days after the second treatment.
Botox is an FDA-approved treatment for treating migraines in adults 18 years of age and older.
How are BOTOX injections performed for Migraines?
Botox is injected around pain fibers that are involved in headaches. Using a very small needle, that feels like a pinprick, the doctor will inject small amounts of Botox into the shallow muscles in the skin. Typically, each treatment involves 31 injections in seven key areas of the head and neck. The medication enters the nerve endings around where it is injected and blocks the release of the pain transmission chemicals, thus preventing activation of the pain networks in the brain.
What should I expect after having BOTOX injections for Migraines?
The most common side effect from Botox shots is a sore neck, and we recommend using an ice pack to reduce the discomfort.
It can take up to six months to see the maximum benefit from Botox, but you can continue taking your regular migraine medications with no risk of a drug interaction.
