This is a new guideline from NICE advising that erenumab can be used for the prevention of migraine, published in March.
I did a blog a couple of months ago on galcanezumab, which was recently approved by NICE for the prevention of migraine, and erenumab has been approved for the same circumstances as galcanezumab.
It comes in two strengths: only the 140mg dose has been approved, as the 70mg dose wasn’t effective enough.
