How often is aimovig injected for migraines?

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]
