Quick Answer: Botox (onabotulinumtoxinA) has been FDA-approved for chronic migraine prevention since 2010. Men who experience 15 or more headache days per month, with at least 8 meeting migraine criteria, may qualify. Treatment involves 31-39 injections across the head and neck every 12 weeks and is covered by most major insurance plans when properly documented. Results build over 2-3 treatment cycles.
The Distinction Between Cosmetic and Medical Botox
This is an important point for men considering Botox cosmetically who also suffer from migraines — and vice versa. The cosmetic use of Botox for wrinkles is separate from its FDA approval for chronic migraine prevention. These are two different indications under the same medication. The migraine approval is based on large randomized controlled trials showing significant reduction in headache days per month. Men who qualify for migraine treatment may find that their provider can bill insurance for the procedure while simultaneously addressing cosmetic concerns — though this requires clear documentation and experienced provider coordination.
The Clinical Definition of Chronic Migraine

Search by Zip Code →Chronic migraine has a specific clinical definition: 15 or more headache days per month for more than 3 months, with at least 8 of those days meeting criteria for migraine with or without aura. This distinguishes it from episodic migraine (fewer than 15 headache days per month), for which Botox is not FDA-approved as preventive treatment. Men who think they might qualify should track their headache days for 1-2 months before seeing a provider — documentation is essential for both diagnosis and insurance coverage.
The FDA-Approved Injection Protocol
The PREEMPT protocol used for chronic migraine involves:
- •Total dose: 155 units of Botox per treatment session
- •Injection sites: 31 fixed points across the forehead, temples, back of the head, neck, and upper shoulders
- •Frequency: Every 12 weeks — approximately 4 times per year
- •Duration until benefit: Most men notice improvement after the second or third treatment cycle (24-36 weeks into treatment)
- •Cumulative effect: The migraine-preventive effect builds over multiple treatments; the first cycle often shows only partial benefit
- •Supplemental injections: Up to 8 additional points can be added at provider discretion based on individual pain patterns
Insurance Coverage and Cost
Ready to find a provider near you?
Search by Zip Code →Botox for chronic migraine is covered by most major US health insurance plans when properly documented — including Medicare and Medicaid. Prior authorization is typically required, and most insurers require documentation that at least two preventive migraine medications have been tried and failed before approving Botox. Commonly required prior treatments include beta-blockers, antidepressants with migraine efficacy (amitriptyline), and anticonvulsants (topiramate, valproate). Without insurance, the 155-unit treatment costs $1,200-$1,800 per session. With insurance, copays typically range $50-$300 per session.
Who administers migraine Botox: The PREEMPT protocol should be managed by a neurologist or headache specialist who can make and document the diagnosis, manage the insurance pre-authorization process, and monitor treatment response over multiple cycles. Cosmetic injectors are not the appropriate providers for this indication. Find medical providers at /find-botox-near-me.
What Men Can Realistically Expect
Clinical trial data shows meaningful improvement in monthly headache days for about 70% of patients, with roughly 50% achieving a significant response defined as 50% or greater reduction in migraine days. For men who respond, the impact is substantial — going from 20+ headache days per month to 10 or fewer is a significant quality-of-life improvement with direct effects on work performance, mood, and daily function. Men who do not respond after 3 complete treatment cycles are generally classified as non-responders and treatment is typically discontinued.

Search by Zip Code →The Relationship Between Migraine and Cosmetic Botox
Many neurologists treating patients for chronic migraine report incidental cosmetic improvement in forehead and glabellar lines as a side effect of the migraine protocol injections. Conversely, some men who start with cosmetic Botox for forehead lines report reduced tension headache frequency as a secondary benefit. For men interested in both outcomes, a provider experienced in both applications — or coordination between a neurologist and an aesthetic provider — can optimize treatment across both goals.
