Chronic migraine
Prevention · Established useChronic-migraine-specific injection protocol. Not an established preventive for episodic migraine and not interchangeable with cosmetic injections.
NICE headache guideline: migraine and cluster headacheOnabotulinumtoxinA (Botox)
OnabotulinumtoxinA (Botox) is one option discussed in migraine care. Clea explains where it sits in the treatment landscape without recommending it for an individual person.

ROLE BY HEADACHE TYPE
Which patterns is this used for?
Frequency and symptoms can overlap: someone can have chronic migraine and vestibular symptoms, for example. Choose a label to explore usual roles, not to select a treatment for yourself.
General information, not personal medical advice. Some uses are off-label or supported by limited evidence. TGA approval, PBS eligibility and individual suitability differ. Do not start, stop or change treatment without your clinician or pharmacist.
Use labels are an editorial guide to the cited sources, not a clinical recommendation or an independent clinical-review badge. Each profile retains its separate review status.
Where it fits
Preventive treatment for selected chronic migraine patients.
Administration
Injections delivered by an appropriately trained clinician.
What we know
PREEMPT trials established benefit in chronic migraine.
Access
PBS criteria and provider requirements apply in Australia.
Mechanism, in plain language.
OnabotulinumtoxinA reduces release of neurotransmitters from peripheral nerve endings. For chronic migraine it is delivered across a defined injection pattern by trained clinicians rather than being used like a cosmetic injection.
Decide what “working” would mean.
For prevention, one attack does not tell you whether the treatment is working. Track headache days, migraine-like days, severity, functional impact and acute-medicine days over the review period your clinician recommends. A useful response can be fewer attacks, less severe attacks, better function or a combination of these.
Questions for the treatment conversation
- What is the goal of using OnabotulinumtoxinA (Botox) in my migraine plan?
- How will we decide whether it is helping enough to continue?
- What side effects or warning signs should I know about?
- Do any of my other medicines, conditions, pregnancy plans or allergies change the discussion?
- What is the current Australian access pathway and likely cost for me?
Give the next review better evidence.
Before and after a treatment change, record migraine-like days, total headache days, acute medicine days, severity and functional impact. If you notice side effects, record what happened and when rather than relying on memory at the next appointment.

DRUGS.COM · EXTERNAL PATIENT REVIEWS
Read the right review category.
Original Drugs.com ratings use a 10-point scale. Read the source condition label and review count before drawing conclusions. “Migraine Prevention” is not a vestibular-only or episodic-only score, and a review category does not establish an approved indication.

Source links only. Clea has not imported ratings or review text. Republishing source scores requires permission; no licensed ratings feed is connected. Drugs.com is US-focused, so medicine names and approved uses may differ from Australia. Reviews are self-selected experiences, not comparative evidence of effectiveness.
CLEA COMMUNITY EXPERIENCE · NOT DRUGS.COM
Compare experiences from the same pattern.
People can report a migraine frequency and a symptom pattern separately, such as chronic plus vestibular. Labels are self-reported, not independently diagnosed or verified. Groups can overlap and cannot establish that one treatment works better than another.
