Fremanezumab (Ajovy) is available on the NHS as a possible treatment for preventing chronic migraine in adults who:
- have had headaches on at least 15 days a month for more than 3 months and at least 8 of those have been migraines
- have tried at least 3 other medicines and they have not worked.
You should only continue taking fremanezumab if it reduces your migraines by at least 30% after 12 weeks of treatment (for example, from 20 days to 14 days each month).
If you are not eligible for fremanezumab but are already having it, you should be able to continue until you and your doctor decide when best to stop.
Is this treatment right for me?
Your healthcare professionals should give you clear information, talk with you about your options and listen carefully to your views and concerns. Your family can be involved too, if you wish. Read more about making decisions about your care.

- What are the risks or side effects? How likely are they?
- How will the treatment affect my day-to-day life?
- What happens if the treatment does not work?
- What happens if I do not want to have treatment? Are there other treatments available?
