What is Praluent Pen?

Praluent Pen is a human monoclonal antibody. It works by helping the liver reduce levels of "bad" cholesterol (low-density lipoprotein, or LDL) circulating in your blood.

Praluent Pen is used together with a low-fat diet and a "statin" medication in people with heterozygous familial hypercholesterolemia (an inherited type of high cholesterol). This condition can cause high blood levels of LDL cholesterol, and can also cause plaque to build up inside your arteries.

Praluent Pen is also used to treat heart disease with plaque build-up in the arteries (atherosclerosis, sometimes called hardening of the arteries).

Praluent Pen may also be used for purposes not listed in this medication guide.

How should I use Praluent Pen?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Praluent Pen is injected under the skin, once every 2 to 4 weeks. You may be shown how to use injections at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes.

Your care provider will show you the best places on your body to inject Praluent Pen. Use a different place each time you give an injection. Do not inject into the same place two times in a row.

If you use Praluent Pen only once every 4 weeks, you will give yourself 2 separate injections at the same time. Use a new syringe or injection pen for each injection. Give each injection into a different place on your body.

Each single-use injection pen or prefilled syringe is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Take the medicine out of the refrigerator and allow it to reach room temperature for 30 to 40 minutes before injecting your dose. Do not heat an injection pen or prefilled syringe, and do not leave the pen at room temperature for longer than 24 hours.

Do not shake this medicine. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

While using Praluent Pen, you may need frequent blood tests.

You should not stop using Praluent Pen without your doctor's advice, or your LDL cholesterol levels may increase.

Praluent Pen is only part of a complete treatment program that also includes diet, statin medication, and regular blood testing. Follow your doctor's instructions very closely.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
