Standard Dosing Schedule for Aimovig
Aimovig (erenumab-aooe) is injected once a month for migraine prevention in adults. Each 140 mg subcutaneous dose uses the auto-injector or prefilled syringe, typically in the abdomen, thigh, or upper arm.[1]
How to Administer the Injection
Patients self-administer at home after training. Rotate injection sites to avoid irritation. The full dose is given in one injection; do not split it.[1]
What If You Miss a Dose?
Inject as soon as possible, then resume monthly schedule from that day. Do not double up. If close to the next dose (within a few days), skip and wait.[1]
Differences from Other Migraine CGRP Inhibitors
- Aimovig: Monthly 140 mg (or 70 mg for some).
- Emgality: Monthly 240 mg after loading dose.
- Ajovy: Monthly 225 mg or quarterly 675 mg.
Aimovig's monthly frequency suits most patients avoiding frequent injections.[2]
Common Patient Questions on Frequency
Patients often ask if dosing can change based on response. Doctors may adjust to 70 mg monthly if 140 mg causes side effects like injection-site reactions, but frequency stays monthly.[1][3]
