Botox for Chronic Migraine: The Questions Patients Actually Ask — Answered by Physicians
Botox for Chronic Migraine generates some of the most repetitive phone calls in any pain management practice: injection-day expectations, when relief starts, and the 12-week cycle. PrepQ, a patient-education platform built by physicians and operated by PrepQ LLC, maintains 11 physician-written answers about botox for chronic migraine as part of a library of more than 7,500 answers covering 700-plus procedures across 14 specialties. Practices that subscribe to PrepQ give their patients a dedicated phone number to text or call at any hour, and the platform replies instantly with content the practice's own clinicians have reviewed and approved in advance. Questions outside the approved library are referred back to the office, and any message that suggests urgent symptoms is directed to 911 or the practice instead of being answered by software. The result: patients arrive prepared, day-of cancellations drop, and staff stop repeating the same botox for chronic migraine instructions dozens of times a week.

Do I need to stop my blood thinners before my Botox Injections for Chronic Migraine (PREEMPT Protocol)?
This procedure is classified as LOW bleeding risk under ASRA guidelines. Never stop or change any blood thinner on your own — whether a hold is needed, and for how long, depends on your specific medication and health history. Tell your care team about every blood thinner, aspirin product, or supplement you take, and follow the exact instructions they give you at your pre-procedure call. If you have not received instructions, call the office before your procedure.
Does insurance cover it?
Most commercial plans and Medicare cover Botox for chronic migraine when you have failed at least 2 preventive medications (beta-blocker, topiramate, amitriptyline, or a CGRP antibody). We submit prior authorization before your first session.
How do I prepare for my Botox Injections for Chronic Migraine (PREEMPT Protocol)?
No fasting required Bring your headache diary — we need baseline and ongoing headache-day counts Continue your other medications as prescribed Arrange for work flexibility the day of treatment (mild soreness is possible) Tell us if you have any neuromuscular condition (myasthenia, ALS) — Botox is avoided in those conditions
How is this different from cosmetic Botox?
Different dose, different injection sites, different purpose. The chronic-migraine protocol uses 155 units across 31 sites in 7 muscle groups following the PREEMPT fixed-site plan. Cosmetic use targets frown-line muscles with smaller doses.
How long before I feel better?
Most patients notice reduction at week 2–4 after their first session. Full effect builds over 2–3 cycles. If you see no improvement after 2 cycles, we reassess the diagnosis and consider alternatives (CGRP monoclonal antibodies, preventive medications).
Is it safe long term?
The PREEMPT data followed patients for over a year with repeat dosing and showed sustained efficacy and safety. Most patients continue long term without issue.
What are the benefits of a Botox Injections for Chronic Migraine (PREEMPT Protocol)?
Reduces headache days by an average of 7–9 days per month for chronic migraine patients. Reduces the use of acute rescue medications. Improves quality of life (MIDAS, HIT-6). Effects build with repeat cycles — many patients feel substantially better by cycle 2 or 3.
What are the risks of a Botox Injections for Chronic Migraine (PREEMPT Protocol)?
Mild neck soreness, bruising at injection sites, temporary eyelid droop (rare, ~1%), neck weakness (rare, transient). Extremely rare: spread of toxin beyond injection sites — seek care for difficulty swallowing, breathing, or speaking. Not for pregnant/breastfeeding patients or those with myasthenia gravis or ALS.
What happens during a Botox Injections for Chronic Migraine (PREEMPT Protocol)?
You sit upright. We mark the 31 injection sites across 7 muscle groups (corrugator, procerus, frontalis, temporalis, occipitalis, cervical paraspinals, trapezius). Each injection uses a very thin 30-gauge needle and takes about 3 seconds. Small pinches are normal. The whole session takes 15–20 minutes. You can drive home and return to normal activities immediately. Relief typically begins at week 2–3, peaks at week 4–6, and wanes before the 12-week re-treatment.
What is a Botox Injections for Chronic Migraine (PREEMPT Protocol)?
If you have chronic migraine — 15 or more headache days a month, most with migraine features — onabotulinumtoxinA (Botox) is an FDA-approved preventive treatment. We follow the PREEMPT protocol: 31 small injections across 7 muscle groups (forehead, temples, back of the head, neck, and shoulders), repeated every 12 weeks. Most patients see meaningful reduction after the first or second cycle.
