Alirocumab

Medication Information Leaflet

What is this medication for?

Alirocumab is a type of monoclonal antibody (a man-made protein that attaches to a target in the body) that increases the liver’s ability to remove bad cholesterol. This lowers the amount of ‘bad cholesterol’ in the blood.

High ‘bad cholesterol’ levels can cause blood vessels to clog up and lead to chest pain (angina), heart attack or stroke. By reducing the amount of bad cholesterol in the body, this medication reduces the risk of future heart attack and stroke.

This medication may also be used for patients with high ‘bad cholesterol’ levels in their blood because of a hereditary condition (a medical condition that runs in the family).

How should I take/use this medication?

Do not stop taking your medication without checking with your healthcare professional.
You may use this medication with or without food.
Use the injection pen as advised by your healthcare professional and as described in the manual.

Before using the pre-filled injection pen,

Do not use the pre-filled pen if it has been frozen or is frozen.
Do not use the pre-filled pen if it has been dropped on a hard surface. Part of the pre-filled pen may be broken even if you cannot see the breakage.
Ensure that the contents of your pre-filled pen appear clear and colourless to slightly yellow before use. Do not use it if it appears cloudy, discoloured, grainy or if particles are seen.
Do not shake the pre-filled pen.
Wait at least 30 minutes for the pre-filled pen to naturally reach room temperature before injecting. Do not warm the pre-filled pen by using a heat source such as hot water or microwave.
Do not remove the blue cap from the pre-filled pen until you are ready to inject.

Using the pre-filled injector pen,

Select and clean your injection site. Always rotate the injection site. Injection sites that can be used include:

Thigh
Stomach area (abdomen), except for a 5 centimetre area around your belly button
Outer area of upper arm (only if someone else is giving you the injection)

Pull the blue cap straight off, only when you are ready to inject. Do not leave the blue cap off for more than 5 minutes. This can dry out the medication.
Pinch your skin firmly to form a fold that is around 5 centimetres wide.
With the blue cap off, put the yellow safety guard on your pinched skin at 90 degrees, right-angled to the skin. Firmly push the pre-filled pen all the way down onto the skin until the yellow safety cover is no longer visible. The pen will not work if the yellow safety cover is not depressed fully.
Do not press the start button until the pen is fully pushed down onto the skin. This button can only be pushed once.
When you are ready to inject, press the start button. You will hear the first click sound.
Keep pushing down the pre-filled pen onto the pinched skin during the injection process. The injection may take about 15 to 20 seconds.
When the injection is completed, the window will turn from clear to yellow. You may hear a soft second click sound. Do not rub or massage the injection site.
Throw the pen and blue cap away properly in a container that cannot be punctured. Do not replace the blue cap back on the pen.
