Why Use BOTOX for Chronic Migraine?
BOTOX is a licensed preventive treatment for Chronic Migraine in the UK and Ireland. It
helps reduce the frequency, severity, and duration of migraine attacks.
“BOTOX significantly reduces migraine days in most patients and can be life-changing."

Who Is It For?
You may be suitable for BOTOX if you:
- Have chronic migraine (15+ headache days per month, with 8+ being migrainous)
- Have tried at least 3 other preventive treatments
- Are aged 18 or over
How Does It Work?
BOTOX is injected into specific muscle areas of the head and neck. It works by blocking pain signals, reducing muscle tension, and calming overactive nerve endings.
Treatments are given every 12 weeks, and benefits often improve over time.
Expected Benefits
- Fewer migraine days per month
- Less need for painkillers or triptans
- Improved sleep, energy, and concentration
- Better quality of life
“Most patients notice improvement by their second or third treatment cycle.”
Is BOTOX Safe?
Yes. BOTOX has been extensively tested and is approved for this use.
However, you should inform us if you:
- Are you pregnant or breastfeeding
- Have a muscle or nerve condition
- Are allergic to BOTOX
