Patient leaflet - Aimovig 70 mg solution for injection in Pre Filled syringe
1. What Aimovig is and what it is used for
Aimovig contains the active substance erenumab. It belongs to a group of medicines called monoclonal antibodies.
Aimovig works by blocking the activity of the CGRP molecule, which has been linked to migraine (CGRP stands for calcitonin gene-related peptide).
Aimovig is used to prevent migraine in adults who have at least 4 migraine days per month when starting treatment with Aimovig.

3. How to use Aimovig
Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.
If your doctor prescribes the 70 mg dose you should have one injection once every 4 weeks. If your doctor prescribes the 140 mg dose you should have either one injection of Aimovig 140 mg or two injections of Aimovig 70 mg once every 4 weeks. If you are having two injections of Aimovig 70 mg, the second injection must be given immediately after the first one at a different injection site. Make sure that you inject the entire contents of both syringes.
Aimovig is given as an injection under your skin (known as a subcutaneous injection). You or your caregiver can give the injection into your abdomen or your thigh. The outer area of your upper arm can also be used as an injection site, but only if someone else is giving you the injection. If you need 2 injections, they should be given in different sites to avoid hardening of the skin and should not be given into areas where the skin is tender, bruised, red or hard.
Your doctor or nurse will give you or your caregiver training in the right way to prepare and inject Aimovig. Do not try to inject Aimovig until this training has been given.
If you have not noticed any treatment effect after 3 months, tell your doctor who will decide whether you should continue treatment.
Aimovig syringes are for single use only.
For detailed instructions on how to inject Aimovig, see “Instructions for use of Aimovig pre-filled syringe” at the end of this leaflet.
If you use more Aimovig than you should

If you forget to use Aimovig
- If you forget an Aimovig dose, take it as soon as possible after you realise.
- Then contact your doctor, who will tell you when you should schedule your next dose. Follow the new schedule exactly as your doctor has told you.
If you stop using Aimovig
Do not stop using Aimovig without talking to your doctor first. Your symptoms may return if you stop the treatment.

Note: Needle is inside the grey needle cap.
General
Before you use the Aimovig pre-filled syringe, read this important information:
Step 1: Prepare
Note: The prescribed dose of Aimovig is either 70 mg or 140 mg. This means that for the 70 mg dose you must inject the contents of one 70 mg single-use syringe. For the 140 mg dose you must inject the contents of either one 140 mg single-use syringe or two 70 mg single-use syringes, one after the other. 


(A)
Remove Aimovig pre-filled syringe(s) from the carton by holding it/them at the barrel. You may need to use either one or two syringes based on your prescribed dose. Do not shake.
To avoid discomfort at the site of injection, leave the syringe(s) at room temperature for at least 30 minutes before injecting.
Note: Do not try to warm the syringe(s) by using a heat source such as hot water or microwave. (B)
Inspect the syringe(s). Make sure the solution you see in the syringe is clear and colourless to light yellow.
Note:
- Do not use the syringe if any part of it appears cracked or broken.
- Do not use the syringe if it has been dropped.
- Do not use the syringe if the needle cap is missing or is not securely attached.
In all cases described above, use a new syringe, and if you are unsure contact your doctor or pharmacist.
(C)


Gather all materials needed for the
injections:
Wash your hands thoroughly with
soap and water.
On a clean, well-lit work surface,
place the:
- New syringe(s)
- Alcohol wipes
- Cotton balls or gauze pads
- Adhesive plasters
- Sharps disposal container
(D)
Prepare and clean the injection site(s).

Only use the following injection sites:
- Thigh
- Stomach area (abdomen) (except for a 5 cm area around the navel)
- Outer area of upper arm (only if someone else is giving you the injection)
Clean the injection site with an alcohol wipe and let the skin dry.
Choose a different site each time you give yourself an injection. If you need to use the same injection site, just make sure it is not the same spot on that site you used last time.
Note:
- After you have cleaned the area, do not touch it again before injecting.
- Do not choose an area where the skin is tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch marks.
Step 2: Get ready
(E)
Pull the grey needle cap straight off and away from your body, only when you are ready to inject. The injection must be administered within 5 minutes. It is normal to see a drop of liquid at the end of the needle.



Note:
- Do not leave the grey needle cap off for more than 5 minutes. This can dry out the medicine.
- Do not twist or bend the grey needle cap.
- Do not put the grey needle cap back onto the syringe once it has been removed.
(F)
Firmly pinch the skin at the injection site.
Note: Keep skin pinched while injecting.
Step 3: Inject
(G)
While pinching, insert the syringe needle into the skin at an angle of 45 to 90 degrees.
Do not place your finger on the plunger while inserting the needle.
(H)
Using slow and constant pressure, push the plunger rod all the way down until it stops moving.



(I)
When done, release your thumb, and gently lift the syringe off of the skin and then release the pinched skin.
Note: When you remove the syringe, if it looks like there is still medicine in the syringe barrel this means you have not received a full dose. Contact your doctor.
Step 4: Finish
(J)
Discard the used syringe and the grey needle cap.
Put the used syringe in a sharps disposal container immediately
after use. Talk to your doctor or pharmacist about proper disposal.
There may be local regulations for disposal.
Note:
- Do not reuse the syringe.
- Do not recycle the syringe or sharps disposal container
Always keep the sharps disposal container out of the reach of
children.
(K)
Examine the injection site.
If there is any blood on the skin, press a cotton ball or gauze pad onto the injection site. Do not rub the injection site. Apply an adhesive plaster if needed.

If your dose is 140 mg and you are using two Aimovig 70 mg syringes, repeat steps 1(D) to 4 with the second syringe to inject the full dose.
