Living with chronic migraines can interrupt every part of your day, including work, family time, and simply trying to rest. When you’re navigating symptoms like throbbing pain, nausea, and light sensitivity, finding a treatment that actually helps can feel like a major relief.
Aimovig (erenumab-aooe) is one option many people turn to for reducing the number of migraine days they experience. But the cost of Aimovig can feel overwhelming, especially if you’re uninsured or your plan doesn’t cover it well.
Understanding how Aimovig is priced — and what steps you can take to lower your costs — can make it easier to plan ahead and find support that fits your budget. Let’s walk through what you can expect to pay for Aimovig and how to save.
How much does Aimovig cost without insurance?
Aimovig’s price without insurance can vary, but it often runs several hundred dollars per month. The exact amount depends on your pharmacy, your dosage, and whether you use discounts or savings programs. It’s also worth noting that lower-cost biosimilars (“generics”) to Aimovig aren’t available. It’s available only as a reference (“brand-name”) product.
Here’s a look at the average retail price for an Aimovig SureClick autoinjector (the most common form of the medication):
In addition, Aimovig is typically dispensed through specialty pharmacies. These pharmacies may require prior authorization before they can fill or ship your prescription, especially if you’re using insurance. They also typically coordinate delivery directly with you, so you’ll need to be available to confirm shipment and storage instructions.
Which factors affect the cost of Aimovig?
What you’ll pay for Aimovig for migraine prevention depends on several factors, including:
Insurance: If you have insurance, the cost will depend on your plan’s coverage details and cost-sharing requirements. You may have to pay out of pocket for a deductible, copays, or coinsurance.
Location: Medication prices vary by location. For example, GoodRx research shows that people living in Milwaukee and New Orleans often pay more for prescription medications, while those in Atlanta and Houston tend to see lower prices.
Dosage: Aimovig comes as prefilled autoinjectors and syringes. The cost may differ depending on which one you fill. Regardless of form, most people inject the medication under the skin once a month.
Pharmacy: Prices for Aimovig can vary depending on which pharmacy you use.
Discounts: You may be able to lower the cost of Aimovig by using a manufacturer copay savings card or patient assistance program.
Does insurance cover Aimovig?
Aimovig is covered by most commercial insurance plans and Medicaid plans. Coverage is also common among Affordable Care Act (ACA) marketplace plans. But across these plan types, prior authorization is required for many enrollees, and step therapy requirements are also frequent. These rules mean your prescriber may need to show that you meet your insurer’s criteria or that you’ve tried other migraine treatments first.
Coverage is far more limited under Medicare plans — less than 10% of Medicare Advantage and Part D plans cover Aimovig. For those that do, prior authorization or step therapy is less common but still possible.
Because requirements can vary significantly from plan to plan, the best way to understand how your insurance covers Aimovig is to check your plan’s formulary (list of covered medications) or contact your insurer directly.
Injection tips: Pharmacists provide expert advice on how to inject Aimovig (erenumab-aooe).
Risk management: Aimovig is generally well tolerated, but some people still report certain side effects.

If your insurance doesn’t cover Aimovig, try these options:
Ask your prescriber about other migraine prevention medications that may be preferred by your plan or cost less out of pocket.
Check to see if you qualify for financial assistance through Aimovig’s manufacturer copay savings card or patient assistance program.
Request a formulary exception from your insurer. Your prescriber may need to submit paperwork and a letter of medical necessity explaining why Aimovig is necessary.
If your insurer denies a formulary exception request, file an appeal.
During the open enrollment period for health insurance, look for a plan that offers better coverage for Aimovig and your other medications.
Ways to save on Aimovig
Aimovig can cost hundreds of dollars if you don’t have insurance. But there are ways to lower your out-of-pocket costs with and without insurance. Here are four ways you could save.
1. See if you qualify for a copay savings card
With the Aimovig Co-Pay Card, some people with commercial insurance may pay as little as $5 per month for their prescription.
This manufacturer-sponsored savings program helps lower out-of-pocket costs for eligible enrollees and can significantly reduce what you spend throughout the year. The card can be used for either the 70 mg/mL or 140 mg/mL doses, and savings are reset annually.
To qualify, you must:
Have commercial insurance that covers Aimovig
Live in the U.S. or one of its territories
Have a valid Aimovig prescription for its FDA-approved use
You won’t be eligible for the copay savings card if you have Medicare, Medicaid, Tricare, Veterans Affairs coverage, or another form of government-funded insurance. You’re also not eligible if you’re uninsured or if your commercial plan doesn’t cover Aimovig.
2. Check if you’re eligible for a patient assistance program
If you don’t qualify for the copay card, you may still be able to receive Aimovig at a reduced cost — or even at no cost — through the manufacturer’s patient assistance program. You can apply online, and eligibility is based on your insurance status and household income. Your prescriber or specialty pharmacy can also help you apply.
To qualify, you must:
Be uninsured
Meet the manufacturer’s income requirements and submit proof of income
Live in the U.S. or one of its territories
Have a valid Aimovig prescription for its FDA-approved use
If you’re approved, the program may provide Aimovig for free for a designated period of time, depending on your eligibility and annual limits.
3. Ask about 90-day supplies
Aimovig is usually administered once a month, and each monthly dose is supplied as a single prefilled autoinjector or syringe. That means you’ll use one device per month, whether your prescription is for the 70 mg/mL or 140 mg/mL dose.
If your insurance plan allows 90-day (3-month) supplies, you could receive three autoinjectors or syringes at once — one for each month. Some people prefer this option for convenience and potential savings over time. That’s because even without insurance, some pharmacies offer better pricing when dispensing multiple months at a time.
Your prescriber can help determine whether a 90-day supply works for your treatment plan and if your insurance will allow larger fill quantities.
4. Tap into your HSA, FSA, or HRA
If you have a health savings account (HSA), a flexible spending account (FSA), or a health reimbursement arrangement (HRA), you can use those tax-free dollars to cover the cost of Aimovig.
FSA funds are valid for a limited time. So you should use any FSA funds you have by the end of the plan year, before they expire. The same isn’t true for HSA funds, though. HSA funds roll over annually and can be used anytime.
The bottom line
Aimovig (erenumab-aooe) is an injectable medication that prevents migraines. The average retail cost of Aimovig without insurance is $913.19. A lower-cost biosimilar isn’t available, but a manufacturer copay card or patient assistance program can help make your prescription more affordable.
Most commercial insurance plans and Affordable Care Act marketplace plans and almost all Medicaid programs cover Aimovig, but many will ask for prior authorization or step therapy first. Coverage is much more limited with Medicare. Since coverage can vary, it’s worth checking your plan to see what’s required and what you might pay.

Methodology
We obtained national prescription coverage data for each medication from Managed Markets Insight & Technology (MMIT). The data reflects health insurance coverage as of December 6, 2025.
We calculated the percentage of enrollees in plans that cover each medication by dividing the number of enrollees covered for the medication within a specific insurance channel (e.g., ACA, Medicare, Medicaid) by the total number of enrollees in all plans within that channel.
We determined the percentage of enrollees in plans with a prior authorization requirement by calculating the proportion of enrollees in plans that required prior authorization for the medication within each channel.
Finally, we measured the percentage of enrollees in plans with a step therapy requirement by calculating the proportion of enrollees in plans that imposed step therapy requirements for the medication in each channel.
These estimates, derived from national MMIT coverage data, provide insight into health insurance coverage for each medication. They take into account restrictions such as prior authorization, step therapy, and quantity limits. The percentages are expressed relative to the total number of enrollees covered by various insurance channels, including ACA plans, commercial (excluding ACA) plans, Medicare, and Medicaid (both state-run and managed care plans).
