What is Aimovig (erenumab)?
Aimovig is a prescription medicine given to adults for the treatment of migraine headaches. It contains the active ingredient erenumab-aooe, a monoclonal antibody.
Erenumab works by blocking the action of a molecule called calcitonin gene-related peptide (CGRP). CGRP normally attaches to receptors on cells in your brain thought to be involved in triggering migraine attacks. Erenumab attaches to these receptors instead of CGRP, stopping it from stimulating the receptors and preventing migraines.
Aimovig is available in injection form as 70 mg/mL solution in a single-dose prefilled autoinjector, and 70 mg/mL solution in a single-dose prefilled syringe.
Aimovig is for subcutaneous use only. Inject into the abdomen, thigh, or upper arm. The recommended dose is 70 mg once monthly. Some patients may require a dosage of 140 mg once monthly.
Take this medication out of the refrigerator before use. Allow the Aimovig autoinjector or syringe to warm up to room temperature for at least 30 minutes. Do not heat this medication any other way. Do not expose to direct sunlight and do not shake this medication.
You are advised to read the full prescribing information provided with this medicine for drug information and patient information, and always speak with your healthcare provider for medical advice about any changes to your dose so they can monitor and evaluate your condition.
