Below is information about Aimovig’s standard dosage.

What is Aimovig’s form?

Aimovig comes as a liquid solution that you’ll inject under your skin using:

  • a single-dose prefilled SureClick auto-injector pen, or
  • a single-dose prefilled syringe

Note: These forms of the drug contain dry natural rubber. If you have a latex allergy, let your doctor know before starting Aimovig.

What strengths does Aimovig come in?

The Aimovig SureClick pen and the syringe each come in two strengths:

  • 70 milligrams per 1 milliliter (mg/ml) of liquid solution
  • 140 mg/ml

What are the standard dosages of Aimovig?

Your doctor will usually prescribe a starting dose of 70 mg of Aimovig per month. If this dosage doesn’t reduce the number of migraine episodes you have, or doesn’t reduce your migraine symptoms enough, your doctor may increase your dosage to 140 mg per month.

The information above describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Is Aimovig taken long term?

Yes, Aimovig is usually taken as a long-term treatment if it’s working to prevent your migraine episodes. If you and your doctor agree that Aimovig is safe and effective for you, it may be prescribed long term.

If you miss an injection of Aimovig, take it as soon as you remember. Since Aimovig is taken once a month, your dosing schedule will be adjusted so that your next dose is a month away.

Do not give yourself two doses of Aimovig at one time. This could increase your risk of serious side effects.

If you need help remembering to take your dose of Aimovig on time, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.

Aimovig is an injectable liquid solution that comes in a prefilled syringe or a prefilled SureClick auto-injector pen.

You’ll be given your first dose of Aimovig at your medical clinic. Then you (or a caregiver) will be shown how to give your injections at home.

You should use each syringe and SureClick pen once for a single dose only. Discard the used syringe or pen in a sharps container after each injection.

While you’re taking Aimovig, consider keeping track of how often you have migraine episodes or symptoms. You can also keep track of possible triggers and the treatments you used. Sharing this information with your doctor can help them make sure your treatment plan is effective.

Do not inject more Aimovig than your doctor prescribes. Injecting more than this can lead to serious side effects.

What to do in case you inject too much Aimovig

Call your doctor right away if you think you’ve injected too much Aimovig. You can also call 800-222-1222 to reach the American Association of Poison Control Centers, or use its online resource. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.

The sections above describe the standard dosages provided by the drug manufacturer. If your doctor recommends Aimovig for you, they will prescribe the dosage that’s right for you.

Remember, you shouldn’t change your dosage of Aimovig without your doctor’s recommendation. Only take Aimovig exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage.

Here are some examples of questions you may want to ask your doctor:

  • Could the higher dosage of Aimovig increase my risk of side effects?
  • Will my dosage of Aimovig be lower than usual if I have high blood pressure?
  • Can I take my Aimovig dosage with other migraine medications?

Can Aimovig be prescribed for injection every other month instead of every month?



It’s not usually recommended to inject Aimovig every other month instead of every month. The drug’s effectiveness at this lower dosage isn’t known.

If you have severe or bothersome side effects (such as constipation), talk with your doctor. It’s possible that taking Aimovig less often may reduce the severity of side effects. Make sure to follow your doctor’s Aimovig dosing instructions, and take Aimovig as often as they recommend.
