What is PRALUENT® (alirocumab)?

Some people need extra help managing their bad cholesterol. Statins can only do so much, but adding PRALUENT to the highest tolerated dose of a statin can help provide additional lowering of bad cholesterol. PRALUENT works differently than statins to lower bad (LDL) cholesterol. It works by blocking a protein (called PCSK9) that may contribute to high levels of bad cholesterol.


PRALUENT is an injectable prescription medicine called a PCSK9 inhibitor. PRALUENT is used along with diet and the highest tolerated dose of a statin in adults with heterozygous familial hypercholesterolemia (an inherited condition that causes high levels of LDL cholesterol) or atherosclerotic heart problems, who need additional lowering of LDL cholesterol.

The effect of PRALUENT on heart problems such as heart attacks, stroke, or death is not known.

It is not known if PRALUENT is safe and effective in children.

Who should not use PRALUENT?

Do not use PRALUENT if you are allergic to alirocumab or to any of the ingredients in PRALUENT.

What should I tell my doctor before using PRALUENT?

Before you start using PRALUENT, tell your doctor about all your medical conditions, including allergies, and if you:

  • Are pregnant or plan to become pregnant. It is not known if PRALUENT will harm your unborn baby. Tell your doctor if you become pregnant while taking PRALUENT.
  • Are breastfeeding or plan to breastfeed. You and your doctor should decide if you will take PRALUENT or breastfeed. You should not do both without talking to your doctor first.

Tell your doctor or pharmacist about any prescription and over-the-counter medicines you are taking or plan to take, including natural or herbal remedies.

How should I use PRALUENT?

See the detailed “Instructions for PRALUENT Pre-filled pen” that come with the patient information about the right way to prepare and give your PRALUENT injections.

  • Use PRALUENT exactly as your doctor tells you to use it. Your doctor will prescribe the dosage that is best for you.
  • If your doctor decides that you or a caregiver can give the injections of PRALUENT, you or your caregiver should receive training on the right way to prepare and administer PRALUENT. Do not try to inject PRALUENT until you have been shown the right way by your doctor or nurse.
  • PRALUENT is injected under the skin (subcutaneously) every 2 weeks or every 4 weeks (monthly).
  • If your doctor prescribes you the monthly dose, you will give yourself 2 separate injections in a row, using a different pen for each injection and two different injection sites.
  • Do not inject PRALUENT together with other injectable medicines at the same injection site.
  • Always check the label of your pen to make sure you have the correct medicine and the correct dose of PRALUENT before each injection.
  • If you forget to use PRALUENT or are not able to take the dose at your regular time, inject your missed dose as soon as you remember, within 7 days. Then, if you inject every 2 weeks take your next dose in 2 weeks from the day you missed your dose or if you inject every 4 weeks take your next dose in 4 weeks from the day you missed your dose. This will put you back on your original schedule.
  • If you missed a dose by more than 7 days and you inject every 2 weeks, wait until your next scheduled dose to re-start PRALUENT or if you inject every 4 weeks, start a new schedule from the time you remember to take your dose.
  • If you are not sure when to re-start PRALUENT, ask your doctor or pharmacist.
  • If you use more PRALUENT than you should, talk to your doctor or pharmacist.
  • Do not stop using PRALUENT without talking with your doctor. If you stop using PRALUENT, your cholesterol levels can increase.
