Migraine can be a debilitating condition, but preventative treatments like Aimovig are changing the landscape. This Aimovig migraine medication, known as the Aimovig shot, offers a new approach for those who experience frequent attacks. In this guide, we'll explore what Aimovig is, how the Aimovig injection works, and what you should consider before starting treatment.

What Is Aimovig?

Aimovig is a brand-name prescription medication containing the active ingredient erenumab. It belongs to a class of drugs called calcitonin gene-related peptide (CGRP) inhibitors, specifically designed to prevent migraine. Unlike acute treatments that stop a migraine after it starts, Aimovig works as a preventive therapy, taken monthly to reduce the frequency of migraine days. According to the FDA, Aimovig was the first CGRP inhibitor approved for migraine prevention.

How Does Aimovig Work?

Aimovig works by blocking the activity of CGRP, a protein that plays a key role in migraine attacks. By binding to the CGRP receptor, erenumab prevents the protein from triggering blood vessel dilation and inflammation associated with migraines. This mechanism targets the underlying biology of migraine rather than just symptoms. In clinical trials, people taking Aimovig experienced fewer monthly migraine days compared to those on placebo.

Who Can Benefit from Aimovig?

Aimovig is intended for adults who experience frequent migraines, typically defined as four or more migraine days per month. It may be an option if other preventive medications have not worked or caused intolerable side effects. However, it's important to discuss your medical history with a healthcare provider, as Aimovig is not suitable for everyone. For example, individuals with severe constipation or certain cardiovascular conditions may need to avoid it.

What to Expect from the Aimovig Injection

Aimovig comes as a prefilled auto-injector or prefilled syringe for self-administration once a month. You can inject it under the skin of your thigh, abdomen, or upper arm. Many people appreciate the convenience of an at-home injection. According to the manufacturer, you should store Aimovig in the refrigerator and let it reach room temperature before injecting to reduce discomfort. Common injection site reactions include redness, swelling, or pain. To help make the process smoother, consider the following tips:

Tips for Using the Aimovig Shot

Rotate injection sites each month to avoid skin irritation.
Use the auto-injector exactly as instructed by your healthcare provider.
Keep a headache diary to track your migraine days and monitor effectiveness over time.
Contact your doctor if you have questions about storage or administration.

Potential Side Effects and Considerations

Like all medications, Aimovig can cause side effects. The most commonly reported ones are injection site reactions and constipation. More serious but less common side effects may include severe constipation with complications, high blood pressure, and allergic reactions. Because Aimovig is a relatively newer medication, long-term safety data is still being collected. The FDA continues to monitor its safety. Always discuss any concerns with your doctor before starting or stopping treatment.
