Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of evolocumab injection in children younger than 10 years of age with HoFH and primary hyperlipidemia. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of evolocumab injection in the elderly. However, elderly patients are more sensitive to the effects of this medicine than younger adults.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Other Interactions

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Proper Use

A nurse or other trained health professional will give you this medicine. It is given as a shot under your skin, usually in the stomach, thighs, or upper arms.

This medicine comes with a patient information leaflet and patient instructions. Read instructions before starting this medicine and with each refill. New information may be given. Follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

Evolocumab injection may sometimes be given at home to patients who do not need to be in the hospital or clinic. If you are using this medicine at home, your doctor will teach you how to prepare and inject the medicine. Be sure that you understand exactly how to use the medicine.

This medicine comes in 3 forms: a single-dose prefilled pen (autoinjector), single-dose prefilled syringe, and a single-use Pushtronex® system (on-body infusor with prefilled cartridge). Your doctor will prescribe the type and dose that is right for you.

You will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems from the injections.

Do not inject on skin areas that are bruised, hard, red, or tender or have cuts, scrapes, infection, scars, or stretch marks.

If you are receiving the 420 milligrams (mg) dose of Repatha®, it can be given: over 5 minutes by using the single-use Pushtronex® system, or by 3 injections consecutively within 30 minutes using the single use prefilled syringe or autoinjector.

The autoinjector pen or prefilled syringe should be removed from the refrigerator and be allowed to reach room temperature for at least 30 minutes before using, or for at least 45 minutes for single-use Pushtronex® system. Do not shake the medicine.

Use each autoinjector pen or syringe only one time. Do not save an open pen or syringe. If the medicine in the pen or syringe has changed color, or if you see particles in it, do not use it.

In addition to this medicine, your doctor may change your diet to one that is low in fat, sugar, and cholesterol. Carefully follow your doctor's order about any special diet.
