Uses

This medication is used by people with a certain inherited bleeding problem (hemophilia A) to help prevent or lessen how often you have bleeding problems. Emicizumab belongs to a class of medications known as monoclonal antibodies. It works by helping your blood to clot normally, which helps prevent bleeding due to hemophilia A. Preventing bleeding can lessen symptoms such as painful swellings, joint pain, pain with movement, and difficulty walking far.

How to Use This Medication

Read the Medication Guide and Instructions for Use provided by your pharmacist before you start using this medication and each time you get a refill. Ask your health care professional how to prepare and use this medication. If you have any questions, ask your doctor or pharmacist.

Inject this medication under the skin as directed by your doctor, usually once a week for the first 4 weeks, followed by a maintenance dose on a regular schedule as prescribed. The injection is given in the thighs, upper arm, or abdomen (at least 2 inches from your belly button). The dosage is based on your medical condition, weight, and response to treatment.

Stop the prophylactic use of bypassing agents the day before starting emicizumab prophylaxis. You may continue prophylaxis with Factor VIII for the first week of emicizumab prophylaxis. Ask your healthcare professional for more information about the use of these other products and what to do if you have breakthrough bleeding.

Take the medication out of the refrigerator 15 minutes before you inject it to allow it to reach room temperature. Do not warm up this medication any other way (for example, do not heat it in the microwave, place it in hot water, or leave it in direct sunlight). Do not shake the medication. Before using, check this product for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the skin you are going to inject into (the injection site) with rubbing alcohol. Change the injection site each time to lessen injury under the skin. Do not inject into moles, scars, or skin that is tender, bruised, red, or hard. To lessen bruising, do not rub the injection site after a shot. Learn how to store and discard medical supplies safely.

Use this medication regularly to get the most benefit from it. To help you remember, use it on the same day each week. It may help to mark your calendar with a reminder.
