What Kind of Medicine Is Erenumab?
Simply put, Erenumab is a medicine used to prevent migraines from happening in the first place. It is not like a normal pain pill that you take after a headache starts. Its main job is to cut down how many migraine attacks you get and make the ones you do get much milder.
This medicine is most commonly sold under the brand name Aimovig. Because it works to stop attacks before they begin, doctors call it a preventive treatment. It is given as a monthly injection just beneath your skin.
Things to Tell Your Doctor Before Starting This Medicine
Before you take your first dose of this medicine, you must share your complete medical history with your doctor. This step is very important to keep you safe and healthy during your treatment plan.
- Tell your doctor if you have any allergies to Erenumab, rubber latex, other medicines, foods, preservatives, or dyes.
- Let your doctor know if you have high blood pressure, as this medicine can sometimes affect blood pressure levels.
- Inform your doctor right away if you are pregnant or planning to get pregnant soon.
- Tell your doctor if you are currently breastfeeding a baby.
Never hide health details from your doctor. Sharing accurate information helps your medical team choose the safest and most effective care option for your body.

Check Availability →How Do You Use This Injection?
This medicine is given as a shot under your skin, known as a subcutaneous injection. Usually, your care team will show you how to give the shot to yourself right at home. Do not feel nervous, because your doctor or nurse will practice with you first.
They will teach you how to prepare the device and how to inject it safely. Always follow their exact instructions.
The most important rule is to use the medicine exactly as your doctor tells you. Never take more doses or inject it more often than prescribed.
What Should You Do With Used Needles?
Managing used sharp tools requires great care to protect yourself and others from accidental pricks. Never throw used needles and syringes straight into your normal household trash bin.
- Always place used needles into a special, puncture-proof sharps container right away after your injection.
- If you do not have a sharps container at home, ask your doctor or pharmacist to provide one for you.
- Dispose of the full container according to local waste guidelines provided by your clinic or public health office.
Is This Medicine Safe for Children?
If you are wondering whether young people can use this treatment, you must talk to a pediatric specialist first. Children and teenagers require special medical attention and different dosing rules compared to adults.
What If You Take Too Much?
If you think you accidentally used too much of this medicine, do not wait. In the US, call 911 or poison control at 1-800-222-1222. In the UK, call 999 or NHS 111. If you are in another region, contact your local emergency department or poisons center right away.
What to Do If You Miss a Dose?
If you forget to take your scheduled dose on time, take it as soon as you remember. However, if it is almost time for your next regular dose, skip the missed dose completely.
Stick to your normal schedule for the next shot. Never take two doses at the same time to make up for a missed one. If you feel confused about your schedule, call your doctor for advice.
What Are the Possible Side Effects?
Like all medicines, Erenumab can cause side effects in some people. While many users tolerate it well, knowing what to look for helps you stay safe.
| Side Effect Category | What to Look For and Do |
|---|---|
| Urgent Side Effects (Call Doctor or ER) | Allergic reactions like skin rash, itching, swelling of your face, lips, or tongue, trouble breathing, chest pain, or a fast, irregular heartbeat. |
| Common Side Effects (Tell Doctor if Bothering You) | Constipation, muscle cramps, or mild pain, redness, and itching at the injection site on your skin. |
This list does not cover every possible side effect. If you notice any other unusual symptoms that worry you, speak with your doctor.
How Should You Store This Medicine?
- Always store this medicine safely in a locked cabinet where children cannot reach it.
- Keep your injection pens in the refrigerator as instructed by your pharmacist, and protect them from direct heat and light.
- Check the expiration date printed on the label, and never use the medicine after that date has passed.
Important reminder: This medicine is meant for you alone. Never give your injection pen to a friend or family member, even if they have the exact same migraine symptoms.
