Alirocumab is a monoclonal antibody that belongs to the class of medications called proprotein convertase inhibitors (PCSK9 inhibitors). It blocks a protein in the liver, allowing the liver to remove more low-density lipoproteins (LDL or "bad" cholesterol) from the blood.
This medication is used in addition to diet and other medications when diet and maximum doses of "statin" cholesterol medication are not enough to lower the LDL levels of people who have high cholesterol levels. Alirocumab is also used to reduce the risk of heart attack, stroke, and a type of chest pain called unstable angina for adults who have been diagnosed with cardiovascular disease.

The recommended starting dose of alirocumab is 75 mg injected subcutaneously (under the skin) every 2 weeks. Depending on the effectiveness of the medication, your doctor may increase your dose to 150 mg every 2 weeks, but most people find that the lower dose is enough. Alternatively, your doctor may recommend a dose of 300 mg injected once every 4 weeks. This will involve 2 separate injections of 150 mg of alirocumab.
Subcutaneous injections are administered in the abdomen, upper arm, or thigh area. Change the injection site with each injection to keep your skin healthy.
Do not use the injection if it is discoloured or if particles are present.

If a family member or caregiver will be giving you the injections, your doctor should instruct them on how to give the injection.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: As with other monoclonal antibodies, alirocumab may cause your body to produce antibodies to "defend" your body from the medication. When this happens, an allergic reaction develops. Often, allergic reactions are experienced as a rash, hives or itching. On rare occasions, a severe allergic reaction may occur, causing difficulty breathing, abdominal cramps, nausea and vomiting, or swelling of the throat (anaphylaxis). Another form of allergic reaction that may occur is hypersensitivity vasculitis, where the blood vessels become inflamed, causing small purplish spots to form on the skin. If you experience any unusual symptoms, contact your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if alirocumab passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children and adolescents less than 18 years old.
