Aimovig (erenumab-aooe) is a once-monthly injectable prescription medication used for the prevention of migraine in adult patients. The brand-name drug was approved by the Food and Drug Administration (FDA) in 2018 and belongs to a class of drugs known as calcitonin gene-related peptide (CGRP) receptor antagonists, or CGRP receptor antagonists. It blocks a protein called CGRP, which is linked to migraine pain and inflammation. By doing so, Aimovig helps reduce how often and how severely migraine attacks occur. 

Aimovig dosage

Aimovig is typically self-administered by the patient, after proper training, or administered by a caregiver. Each autoinjector contains a single dose of Aimovig and should be discarded after use. Aimovig is available in the following injectable formulations:

• 70 mg/mL single-dose prefilled autoinjector
• 140 mg/mL single-dose prefilled autoinjector

The recommended dose of Aimovig is either 70 mg or 140 mg, injected once per month. Note that Aimovig is used to prevent migraine. It is not used for acute treatment to stop a migraine. The medicine is administered by subcutaneous injection, under the skin of the thigh, abdomen, or upper arm. Aimovig should not be injected into skin that is hard, red, bruised, or tender. 

Regardless of dosage, Aimovig should be stored in the original cartin in the refrigerator, protected from light until it is ready to use. Let it come to room temperature for at least 30 minutes once you take it out of the refrigerator and are ready to use it. You must use it within seven days of bringing it to room temperature. Discard it after seven days. 

Aimovig 70 mg vs. 140 mg: Which is better for migraine prevention?

Your healthcare provider’s choice of dosage may depend on how well previous migraine treatments have worked for you.

A review of clinical trials published in 2019 found that the 140 mg dose of Aimovig might offer more benefits compared to the 70 mg dose for individuals who have not had success with other preventive migraine treatments. Researchers observed that patients with a history of failed treatments experienced better results with the higher dose, both for episodic and chronic migraine. 

Another clinical study published in 2022 reviewed various sources to compare the effectiveness and safety of the 70 mg and 140 mg doses of Aimovig. This review found that, while the 70 mg dose is usually the starting point in treatment, the 140 mg dose may offer more benefits, especially for patients who have not responded well to other treatments or have high medication use.

Episodic migraine (EM) involves having 0 to 14 headache days per month, while chronic migraine (CM) is characterized by 15 or more headache days per month. In some cases, EM can progress to CM. The 2022 study highlighted that the higher 140 mg dose generally provides greater benefits in reducing monthly migraine days and preventing the progression from EM to CM. Importantly, there are no additional downsides or risks of using the higher 140 mg dose. For those who start on the 70 mg dose but do not see enough improvement, moving to the 140 mg dose (under the guidance of a healthcare provider) might be a better option before trying a different medication. Overall, this suggests that the 140 mg dose could be more effective for some patients.
