It takes approximately 154 days (22 weeks, or over 5 months) for Aimovig to be eliminated out of your system.

Aimovig is a prescription medicine injected under the skin once a month for the preventive treatment of migraine in adults.

  • The elimination half life of Aimovig (erenumab) is 28 days. This is the time it takes for your body to reduce the plasma levels by one-half.
  • It usually takes around 5.5 x elimination half-life for a drug to be eliminated from your system.
  • For example, 5.5 x 28 days = 154 days which is 22 weeks, or over 5 months for Aimovig to be cleared from you body.

The actual half-life can vary from person to person due to patient-specific and drug-specific variables. Factors such as how well a drug is absorbed, distributed throughout the body, or excreted can affect the half-life.

Can I use Aimovig more than one time per month?

Aimovig is approved by the FDA to be injected only once per month. Your doctor will determine the best dose for you and your migraine symptoms. Speak with your doctor about your dosing schedule.

What if I miss a dose of Aimovig?

If you miss a dose of Aimovig, administer it as soon as possible. Do not double your dose to make up for missed dose. Thereafter, your Aimovig dose can be scheduled monthly from the date of your last dose. If you have questions about your dose or when to administer it, call your doctor.

Bottom Line

  • It takes about 154 days (22 weeks, or 5.5 months) for Aimovig to be eliminated out of your body.
  • The elimination half life of Aimovig (erenumab) is 28 days. This is the time it takes for your body to reduce the plasma levels by one-half.
  • Aimovig is a long-acting medicine for migraine treatment. It approved by the FDA to be injected subcutaneously (under the skin) once per month.
