Treatment information
Understanding your pathway
What is the treatment?
Botulinum toxin type A injections may be used to prevent headaches in selected adults with chronic migraine. This page concerns migraine treatment, not cosmetic injections or a general cure for muscle pain. The medicine, indication and treatment plan should be confirmed with the clinician before any decision. [1][2][3]
Who may be considered?
A headache assessment establishes the pattern and considers preventive treatments already tried and medication overuse. NICE defines chronic migraine for this recommendation as at least 15 headache days per month, including at least 8 migraine days. Its UK eligibility criteria do not determine Australian prescribing or subsidy eligibility. [1][2][3]
Assessment, preparation and consent
Before deciding, discuss your diagnosis, previous treatment, medicines and relevant health conditions. Tell the clinician about allergies, infection, blood-thinning medicines, diabetes and possible pregnancy. Do not stop prescribed medicines yourself. Ask what alternatives are available, including not having a procedure, and allow time to consider the benefits, uncertainty and risks that matter to you. [4]
What happens during treatment?
Treatment involves injections into specified head and neck muscle sites according to the selected product and protocol. A headache diary helps assess frequency and impact before and after treatment. Timing, repeat treatment and stopping rules need a clinician-led plan, rather than indefinite injections without documented response. [1][2][3]
Risks and safety considerations
Possible adverse effects include injection-site pain and local muscle weakness, including eyelid droop or neck weakness. Product-specific information must be discussed. Seek urgent medical help for breathing or swallowing difficulty or a severe allergic reaction. Tell the clinician about other medicines and conditions that affect muscles or nerves. [1][2][3]
Recovery and when to seek help
Follow the written instructions for transport, supervision, medicines, activity and driving. Recovery depends on the treatment and your health, so a fixed return-to-work date cannot be promised. Ask who to contact outside clinic hours. Seek urgent assessment for fever with worsening pain, new weakness or other unexpected neurological symptoms. Call 000 for breathing difficulty, collapse or another medical emergency. [5][4]
Expected benefit and limitations
Benefit is not guaranteed and this is preventive treatment, not immediate relief for a sudden severe headache. Review headache days, function and adverse effects against agreed criteria. Other preventive and acute treatments may still be needed. A change in headache pattern or new neurological symptoms requires assessment regardless of treatment history. [1][2][3]
Follow-up and rehabilitation
Before treatment, choose a practical goal such as walking, sleep or a daily task. Record changes in that activity, pain and any adverse effects, then discuss them at follow-up. Ask what degree of change would justify further treatment and what would lead to stopping or changing the plan. Rehabilitation and self-management may remain part of care even if symptoms improve. [4][6]
Questions to bring to your appointment
Ask which structure is being targeted, why this approach is being considered and how strong the evidence is for your diagnosis. Clarify costs, the planned review date and any practical help you may need at home. Bring previous reports and your medicine list so the discussion can address your circumstances rather than a generic treatment pathway.
