Aimovig Dosages for Adults: Your GoodRx Guide

If you experience migraines, you’re aware that an attack can bring your routine to a halt. Treatments for migraine have improved over the past several years, making it easier to treat attacks when they pop up. But what about medications that can prevent attacks from happening in the first place?

Aimovig (erenumab-aooe) is an injectable medication that’s FDA approved to prevent migraines in adults. It’s a calcitonin gene-related peptide antagonist, a newer class of migraine medications. As with all medications, getting the right dosage is key to ensuring a safe and effective treatment.

In this article, we’ll review typical Aimovig dosages, as well as what to do if you miss a dose or think you took too much.

What’s the typical Aimovig dosage?

The recommended starting Aimovig dosage for migraine prevention is 70 mg injected beneath the skin once a month. This can be increased to a maximum dosage of 140 mg once per month, depending on your response.

Aimovig comes as a single-dose, prefilled syringe and an autoinjector pen. You’ll use a new syringe or pen for each dose. You can inject Aimovig in your stomach, thigh, or upper arm. But avoid injecting it into skin that is discolored, scarred, or injured in any way. This lowers your risk for injection site reactions.

When you’re first prescribed Aimovig, a healthcare professional will show you how to give yourself injections at home. If you have questions about injecting Aimovig, ask your healthcare team.

Good to know: You should store Aimovig in the fridge. But it’s a good idea to take your syringe or pen out of the fridge 30 minutes before you inject it. This helps make the injection more comfortable. But it also ensures the full dose is injected. If your carton of Aimovig has been at room temperature for longer than 7 days, you should discard it because it may not work as well.

Is there a biosimilar for Aimovig?

No, there isn’t a biosimilar (“generic”) for Aimovig.

A biosimilar is a close (but not identical) copy of a biologic medication. Biologic medications are made from natural sources, such as proteins or sugars, so it’s impossible to make an exact copy. But in order to be FDA approved, biosimilars must be just as safe and effective as the reference (“brand-name”) biologic they’re based on.

Are there any dosage adjustments for health conditions?

Some medications have different dosages for conditions like kidney or liver disease. But there are no recommended Aimovig dosage adjustments for people with certain health conditions. There are also no recommended dosage changes based on drug interactions.

Your prescriber will determine the right Aimovig dosage for you based on your symptoms and any side effects you experience. This dosage could change over time, depending on your response.

What happens if you miss a dose of Aimovig?

If you miss a dose of Aimovig, administer the missed dose as soon as possible. Missing doses can cause your migraines to return, worsen, or happen more frequently.

Since Aimovig is administered once a month, you shouldn’t skip the missed dose. Instead, inject it once you realize it’s past due. Then give your next dose one month after you inject the missed one and continue that schedule.

For example, let’s say you typically inject Aimovig on the fifth day of the month. One month, on the eighth day, you realize you forgot your dose. You should inject Aimovig that day. Then you should administer your next Aimovig dose on the eighth day of the following month and each month thereafter.

What should you do if you take too much Aimovig?

Overdose wasn’t reported in Aimovig’s clinical trials. And there hasn’t been much research on whether excessively high doses are harmful. But since Aimovig comes as a single-use syringe or pen, it’s unlikely that you’d accidentally inject too much.

Regardless, if you think you’ve taken too much Aimovig, contact your prescriber. You can also contact Poison Control online or at 1-800-222-1222 for guidance.
