What is Aimovig Autoinjector?

70 mg/mL is the most commonly prescribed dosage. All shots are FDA-approved to be taken monthly. All contents should be opalescent to clear, or colorless to yellow.

How do you use Aimovig Autoinjector?

Aimovig comes in a single-dose prefilled autoinjector or single-dose prefilled syringe. Both are intended for you to use at home. Before your first use, read the prescribing information and listen to all instructions for use that your healthcare provider gives you so that you feel comfortable administering the shot at home.

Aimovig should be kept in the refrigerator between 36°F to 46°F (2°C to 8°C) in the original carton until you are ready to give an injection. Before you give a dose, take it out of the fridge and let it sit at room temperature for at least 30 minutes away from direct sunlight. This is so that it minimizes discomfort for you and administers the entire dose.

Do not warm it up by using a heat source like hot water or a microwave. As you’re preparing for the shot, don’t shake the product. As with most medicines, inspect for any discoloration or inconsistent matter before using. If the treatment is cloudy, discolored, or contains particles or flakes, do not use it.

Pull the white or orange cap off the autoinjector, but make sure not to touch the safety guards before you inject Aimovig. Even after you press the start button, the medicine will only be administered when the safety guard is pushed into the autoinjector. Administer Aimovig subcutaneously (under the skin) in your upper arm, thigh, or abdomen. Do not inject anywhere the skin is tender, bruised, hard, or red.
