Treatment
Botox for Chronic Migraine
Overview
Botox is best known for cosmetic use, but it is also an FDA-approved treatment to prevent chronic migraine. For people who live with frequent, disabling headaches, it can be one of the most effective preventive options available.
Chronic migraine means having a headache on 15 or more days a month, with migraine features on at least 8 of those days. At that frequency, migraine can take over work, sleep, and daily life. Botox is designed for exactly this group: it is a preventive treatment meant to reduce how often migraines happen, not a remedy for a single attack.
Given as a series of small injections about every 12 weeks, Botox works gradually. Many people find that their headache days become fewer and their attacks less severe over the course of treatment. Because a proper diagnosis matters, our board-certified providers first confirm that Botox is the right fit before starting.
How it works
How Botox prevents migraine
Botox (onabotulinumtoxinA) is given as a series of small injections around the head and neck. It is thought to work by:
- Blocking the release of chemicals involved in pain signaling
- Calming the nerve endings that trigger migraine attacks
- Reducing how often migraines happen over time, rather than stopping one in progress
Botox is a preventive treatment. It is not used to relieve a migraine that has already started.
Candidates
Who Botox is for
Botox is FDA-approved for adults with chronic migraine. You may be a candidate if you have:
- Migraine or headache on 15 or more days a month
- Headaches that last 4 hours or more
- Migraines that have not responded well to other preventive medications
Botox is not FDA-approved for episodic (occasional) migraine. Our providers will confirm whether it is right for you.

- Full benefit can take two treatment cycles, so we usually recommend giving it about six months
- Your provider tracks your headache days and adjusts the plan as needed
Safety
Is Botox for migraine safe?

Our Approach
How we help
Migraine care is not one-size-fits-all. Our board-certified providers first confirm that your headaches are chronic migraine and that Botox is an appropriate option, then deliver treatment in our office and track your progress over time. For many people with frequent migraine, Botox can meaningfully reduce how often attacks occur and improve day-to-day life.
Good to Know
Botox for Chronic Migraine: Frequently Asked Questions
Does Botox really help migraines?
Yes, for chronic migraine. Botox is FDA-approved as a preventive treatment for adults who have migraine or headache on 15 or more days a month. In studies, it reduced the number of headache days per month. It works to prevent attacks over time and does not stop a migraine that has already started.
Who is a candidate for Botox for migraine?
Botox is intended for adults with chronic migraine, generally defined as 15 or more headache days a month with headaches lasting 4 hours or longer. It is often considered when other preventive medications have not worked well enough. It is not FDA-approved for episodic (occasional) migraine, so a neurologist should confirm it is the right fit.
How does Botox prevent migraines?
Botox is injected in small amounts around the head and neck, where it is thought to block the release of chemicals involved in pain signaling and calm the nerve endings that set off migraine attacks. The result is fewer and often less severe migraines over time.
How often do I need Botox for migraine?
Treatments are given about every 12 weeks. Consistent, scheduled treatment is important, because the preventive benefit builds over time and can fade if treatments are stopped.
Does Botox for migraine hurt?
The injections use a very small needle and most people tolerate them well. The appointment takes only about 15 minutes, and there is no downtime, so you can return to your day right away.
How long does it take for Botox to work for migraines?
Some people notice improvement within a few weeks, but the full benefit can take two treatment cycles. For that reason, we usually recommend giving Botox about six months before deciding how well it is working.
Is Botox for migraine covered by insurance?
Many insurance plans cover Botox for chronic migraine, often after a prior authorization and after other preventive medications have been tried. Coverage varies by plan, and our team can help you understand your options.
