I’m on Nurtec as a preventative through ASPN pharmacy.
All the stuff I’m about to share came directly from my healthcare professional at the migraine clinic.
They explained to me that Nurtec typically takes 3-4 months to build up and be effective at raising the threshold so I should have fewer migraines/VMs or they may be less severe or the episode duration may be shorter. Basically, echoing comments above.
I asked the question about classic migraine vs. VM, since I get both, sometimes separately, sometimes together. They said that the various migraine meds (abortive or preventative) work differently for different individuals and the only way to figure out what works for me is trial and error.
When I had a particularly bad episode that included excessive dizziness, my clinic prescribed Meclizine (it’s OTC, but cheaper as Rx when covered). The Meclizine worked well for me for the excessive dizziness flare ups, but everyone is different.
They also explained ASPN as a specialty pharmacy that works with the drug manufacturer and provides discounted (or free) Nurtec while working with my insurance to get it covered. I think my insurance denied it twice, then finally approved coverage.
