Hi
Thank you for sharing your concerns and questions with us. Like , I've not tried infusions/injections of the new CGRP medications. We've heard from folks who have good results, and others not so much. Aimovig, Ajovy and Emgality are injections, while Vyepti is an infusion. Have you seen this information on them?

It's important to remember migraine prevention medications don't get rid of or "cure" migraine disease - they work to reduce attack frequency and severity. At this point there is no cure for migraine, hopefully we'll see one in our lifetime. The thing is like you, many of us are on a combination of medications, I sure am.
I hear you about high dose Topamax. At one point I was on 400 mg, which was ridiculous - still had migraine attacks. If you don't think you're seeing any benefit from it, please talk to your doctor about it and try not to lose hope. There are over 100 medications, supplements, devices, complementary therapies and lifestyle modifications that can be used to manage migraine disease and most of us are on a combination of these.
