Why is this medication prescribed?
Alirocumab injection is used along with diet and certain cholesterol-lowering medications (HMG-CoA reductase inhibitors [statins]) in people who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally) or in people with cardiovascular disease to further decrease the amount of low-density lipoprotein (LDL) cholesterol (‘bad cholesterol’) in the blood. Alirocumab injection is in a class of medications called proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor monoclonal antibodies. It works by blocking the production of LDL cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
Accumulation of cholesterol along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body.
How should this medicine be used?
Alirocumab injection comes as a solution (liquid) in a prefilled syringe and a prefilled dosing pen to inject subcutaneously (just under the skin) once every 2 weeks. Use alirocumab injection at around the same time every 2 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use alirocumab injection exactly as directed. Do not use more or less of this medication or use it more often or for a longer period of time than prescribed by your doctor.
After 4 to 8 weeks of therapy, your doctor may increase your dose depending on your response to this medication.
Alirocumab injection helps to control cholesterol levels, but does not cure these conditions. Continue to use alirocumab injection even if you feel well. Do not stop using alirocumab injection without talking to your doctor.
Alirocumab injection comes in prefilled dosing pens and prefilled syringes that contain enough medication for one dose. It may take up to 20 seconds to inject the medication. Always inject alirocumab in its own prefilled dosing pen or syringe; never mix it with any other medication. Dispose of used needles, syringes, and devices in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.
You can inject alirocumab injection in your thigh, upper arms, or stomach area, except for the 2-inch area around your navel (belly button) and near your waistline. Use a different spot for each injection. Do not inject into an area where the skin is sore, red, bruised, sunburned, infected, or injured in any way or into areas with visible veins, scars, rashes, or stretch marks.
Carefully read the manufacturer’s instructions for use that comes with the medication. These instructions describe how to inject a dose of alirocumab injection. Be sure to ask your pharmacist or doctor if you have any questions about how to inject this medication.
Remove the prefilled syringe or prefilled dosing pen from the refrigerator and allow it to warm to room temperature for about 30 to 40 minutes before using it. Do not use the syringe or dosing pen if it has been at room temperature for 24 hours or longer. Do not put the prefilled syringe or prefilled dosing pen back in the refrigerator after it has been warmed to room temperature.
Before you use alirocumab injection, look at the solution in the prefilled syringe or pen or closely. The medication should be clear to pale yellow and free of floating particles. Do not shake the prefilled syringe or prefilled dosing pen containing alirocumab injection.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
