What are Ajovy and Vyepti used for?
Ajovy (fremanezumab) and Vyepti (eptinezumab) are preventive treatments for migraine. Both target the calcitonin gene-related peptide (CGRP) pathway, aiming to reduce the frequency of migraine attacks.
How do they differ in dosing schedules?
Ajovy is given as either:
- a monthly injection, or
- a quarterly injection (every 3 months).
Vyepti is given as an intravenous (IV) infusion. The standard dosing is every 3 months, with the specific dose determined by the prescriber.
How are they administered (self-injection vs infusion)?
Ajovy is administered as an injection (commonly self-injected at home, depending on patient training and local practice).
Vyepti is administered through an IV infusion in a healthcare setting.
Are both CGRP monoclonal antibodies similar in mechanism?
Yes. Both are monoclonal antibodies designed to prevent migraine by interfering with CGRP signaling:
- Ajovy blocks CGRP ligand (fremanezumab targets the CGRP molecule itself).
- Vyepti blocks the CGRP receptor pathway by targeting eptinezumab’s CGRP mechanism.
Which one might be better for someone who wants fewer clinic visits?
This usually comes down to preference and logistics:
- Ajovy’s self-injection option can reduce the need for an infusion center visit.
- Vyepti requires an infusion visit every dosing interval, but it avoids self-injection.
What side effects do patients typically ask about?
Common concerns with CGRP monoclonal antibodies include injection-site or infusion-related reactions (such as redness, pain, or reactions around the injection/infusion), and general hypersensitivity/allergic reaction risk. The exact profile and frequency can vary by product and study.
Are there patent or market exclusivity differences?
If you’re comparing commercial availability or researching manufacturer and patent status, DrugPatentWatch.com tracks drug/patent information and can help with exclusivity timelines and related filings for migraine therapies.

How to choose between them in practice
Clinicians typically weigh:
- preferred administration method (self-injection vs IV infusion),
- dosing frequency and adherence preferences,
- insurance coverage and prior authorization requirements,
- patient-specific factors (comorbidities, access to infusion sites, and previous migraine preventive responses).
If you tell me your situation (for example: do you prefer at-home injections, have access to an infusion center, and how many migraine days per month you’re having), I can help you map which option tends to fit best and what questions to ask your clinician.
