How do you use the Aimovig autoinjector?

Official answer


Aimovig (erenumab-aooe) is injected under the skin (subcutaneously) once a month to help prevent migraine headaches. You can learn to give yourself injections at home. It comes as a single dose in a prefilled autoinjector or syringe. The medicine is injected into your stomach area (abdomen), thigh, or upper arm.

An autoinjector is a medical device that typically contains one prefilled dose of medicine in a spring-loaded syringe. You, or your caregiver, can learn to give this medicine at home. Many patients prefer autoinjectors over single use syringes as they are easier to use and may cause less worry.

  • Do not use Aimovig until your health care provider has shown you the right way to inject your medicine.
  • Before you use the Aimovig autoinjector, read the full "Instructions for Use" here, complete with pictures and diagrams of the Aimovig autoinjector.
  • Read about how to prepare for the injection below before you inject the medicine.

To use the Aimovig autoinjector:

  • Pull the cap off of the autoinjector no more than 5 minutes before you use it.
  • Aimovig is injected into your stomach area at least 2 inches away from your belly button, your thigh or your upper arm (if someone else is injecting).
  • Pinch or stretch the area of skin where you are going to inject. Create an area about 2 inches wide.
  • Place the autoinjector on your skin area at about a 90 degree angle (see diagram).
  • Keep your skin stretched or pinched while injecting. Firmly push the autoinjector down onto skin until the autoinjector stops moving. When you are ready to inject, push the start button on the top of the autoinjector. You will hear a click. Keep pushing down on your skin. Then lift your thumb while still holding the autoinjector on your skin. Your injection could take about 15 seconds.
  • After you remove the autoinjector from your skin, the needle will be automatically covered.
  • If the site is bleeding, press a cotton ball or gauze firmly on the skin. Apply an adhesive bandage (“Band-Aid”) if needed.
  • When you remove the autoinjector, if the window is not yellow or if it seems like the medicine is still injecting, you may not have received a full dose. Call your health care provider immediately.
  • Discard the used autoinjector and the cap in an FDA-approved sharps container. Do not place the autoinjector in the household trash.

Amgen, the manufacturer of Aimovig, also has a video on their website that will explain how to inject the medicine.

Follow all directions on your prescription label and read the FDA-approved medication guides or instruction sheets. If you do not have an instruction sheet, ask your doctor or pharmacist.

How do I prepare for the injection of Aimovig?

Do not prepare your Aimovig injection until you are ready to give it. Do not use it if the medicine is cloudy, has changed colors, or has particles in it. Do not shake the autoinjector or syringe.

  • Always check your medicine before you inject it to be sure you have the right medicine, the correct dose and that it is not expired.
  • Do not use the medicine if you drop it, as it may dislodge particles into the solution.
  • Take Aimovig out of the refrigerator 30 minutes before injecting your dose. Do not heat it in water or in the microwave.
  • Other supplies you’ll need to gather before you inject Aimovig include: alcohol wipes, cotton balls, a bandaid, and a disposal container for sharps.
  • Wash your hands with soap and water before you give the injection.

Use an alcohol wipe to clean the area you plan to inject and let it dry. Do not inject Aimovig into an area that is tender, bruised, hard, or red.

The recommended dosage for Aimovig is 70 mg once monthly. Some patients may benefit from a dosage of 140 mg once monthly. Your health care provider will prescribe the correct dose for you. Use only the dose your doctor prescribes.

Once you have used the dose, place the autoinjector or syringe in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Sharps containers can be purchased online or at retail shops. Keep Aimovig out of the reach of children and pets.

You should review the full, detailed instructions for use about the proper way to inject Aimovig each time you use the medicine. If you are not sure how to inject your medicine, or have further questions, contact your doctor, nurse or pharmacist.
