Botox for Migraines: FDA-Approved Relief for Chronic Migraine
Botox (onabotulinumtoxinA) is FDA-approved for the prevention of chronic migraines — defined as 15 or more headache days per month. For patients with chronic migraine, this treatment changes daily life. Dr. Ashar performs the full standardized PREEMPT protocol.
Botox for Chronic Migraine: How and Why It Works
Botox was approved by the FDA for chronic migraine prevention in 2010 — the first preventative treatment approved specifically for this indication. Clinical trials (the PREEMPT trials) demonstrated that patients treated with Botox experienced significantly fewer headache days per month compared to placebo, with the benefit building over multiple treatment cycles. The mechanism is believed to involve blocking peripheral pain signals that initiate the migraine cascade before they reach the central nervous system.
The treatment involves injections at 31-39 sites across the head and neck — forehead, temples, back of the head, neck, and shoulders — using the standardized PREEMPT protocol. Treatment is administered every 12 weeks. Most patients see improvement by their second or third treatment cycle, with continued improvement over the first year. Dr. Ashar evaluates diagnostic criteria and headache history before initiating treatment to confirm candidacy.
Botox for chronic migraine is covered by many commercial insurance plans and Medicare when prescribed by a qualified provider with appropriate documentation. Tactus Health is a direct-pay practice and cannot bill insurance directly. However, Dr. Ashar will provide a detailed superbill with the appropriate diagnosis codes (ICD-10: G43.7xx) and procedure codes (CPT: 64615) so you can submit for out-of-network reimbursement. Contact your insurer before your first appointment to ask about out-of-network benefits for this specific procedure.
All Botox treatments at Tactus Health are performed by Dr. Ashar N., DNP, APRN, FNP-C, not a technician. Every treatment includes a two-week follow-up assessment.
Frequently Asked Questions
The FDA indication is specifically for chronic migraine — defined as 15 or more headache days per month, with at least 8 of those being migraines. Episodic migraine (fewer than 15 days/month) is not an approved indication, though some providers treat it off-label. Dr. Ashar will review your headache history and determine eligibility during consultation. Accurate headache diary records are helpful to bring to that appointment.
Most patients see meaningful reduction in headache frequency by their second or third treatment, at 12 and 24 weeks. Some notice improvement after the first treatment. Full benefit typically develops over 6-9 months. This is not a treatment that works immediately — patients need to commit to at least 2-3 treatment cycles before evaluating whether it is working for them.
Botox for chronic migraine is frequently covered by insurance when the diagnosis is documented and conservative treatments have been tried. Tactus Health is a direct-pay practice and cannot bill insurance directly, but Dr. Ashar provides a detailed superbill with the appropriate ICD-10 and CPT codes so you can submit for out-of-network reimbursement. Call your insurer before your appointment and ask specifically about out-of-network coverage for CPT code 64615.
PREEMPT stands for Phase 3 Research Evaluating Migraine Prophylaxis Therapy — the two clinical trials that established the FDA approval. The PREEMPT protocol is the standardized injection map: 31 fixed sites across the forehead, temples, occiput, neck, and trapezius muscles, plus up to 8 additional variable sites based on individual headache patterns. Dr. Ashar performs the full standardized protocol, not a simplified or abbreviated version.
Yes. Botox is a preventative treatment and can be used alongside acute migraine medications such as triptans, NSAIDs, or gepants. It is also compatible with other preventative medications if you are already taking them. Dr. Ashar will review your complete medication list during consultation to ensure there are no interactions and to assess whether any adjustments make sense as Botox takes effect over the first several months.
