Standard Dosing Schedule for Aimovig
Aimovig (erenumab) is injected once monthly for migraine prevention in adults. Each dose is 70 mg or 140 mg subcutaneously using the prefilled autoinjector or syringe.[1]
How to Administer the Injection
Patients self-inject under the skin in the abdomen, thigh, or upper arm. Rotate sites to avoid irritation. The full dose goes in with one press of the autoinjector; it takes about 30 seconds. Inject at the same time each month, like the first day.[1][2]
Adjusting Dose for Effectiveness
Start with 70 mg monthly. Doctors may increase to 140 mg (two 70 mg injections) if migraines persist after 3 months. No evidence supports more frequent dosing.[1]
What If You Miss a Dose?
Inject as soon as possible, then resume monthly schedule. If next dose is within 7 days, skip the missed one—don't double up.[1]
Who Should Avoid or Adjust Aimovig
Not for children under 18 or acute migraine treatment. Use caution with severe liver issues; no dose change needed for kidney problems. Pregnancy data limited—discuss risks with doctor.[1][2]
Common Side Effects Patients Report
Injection site reactions (pain, redness) hit about 45% of users. Constipation in 10%; high blood pressure in 4-8%. Rare allergic reactions need immediate care.[1]
