Zilucoplan Injection

WHY is this medicine prescribed?

Zilucoplan injection is used to treat myasthenia gravis (MG; a disorder of the nervous system that causes muscle weakness) in certain adult patients. Zilucoplan is in a class of medications called compliment inhibitors. It works by stopping the compliment system from damaging the acetylcholine receptors on the muscles, which is what causes the symptoms of MG.

HOW should this medicine be used?

Zilucoplan injection comes as a prefilled dosing pen to inject subcutaneously (under the skin) by yourself at home. It is usually injected once a day. Inject zilucoplan at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use zilucoplan exactly as directed. Do not use more or less of it or take it more often than prescribed by your doctor.

You will receive your first subcutaneous dose of zilucoplan injection in your doctor's office. After that, your doctor may allow you to inject zilucoplan yourself or have a friend or relative perform the injections. Before you use zilucoplan injection yourself the first time, read the written instructions that come with it. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it.

Before you use zilucoplan injection yourself the first time, read the written instructions that come with it. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it.

You can inject zilucoplan injection anywhere on front of your thighs (upper leg) or abdomen (stomach) except your navel and the area 2 inches (5 centimeters) around it. If someone else is giving you the injection, that person can also inject the medication into your upper, outer arms. Use a different site for each injection to reduce the chances of soreness or redness. Do not inject into an area where the skin is tender, bruised, red, or hard or where you have scars or stretch marks.

You can store prefilled syringes at room temperature or in the refrigerator. If storing in the refrigerator, remove the prefilled dosing pen from the refrigerator and allow it to warm to room temperature for 30-45 minutes before using it. Take it out of its carton, and allow it to rest on a flat surface so that it can warm to room temperature. Do not try to warm the medication by heating it in a microwave, placing it in hot water, or through any other method.

Do not remove the cap from the prefilled dosing pen while the medication is warming. You should remove the cap right before you inject the medication. Do not replace the cap after you remove it. Do not use the device if you drop it on the floor.

Never shake the prefilled dosing pen. This may damage the medication.

Always look at zilucoplan prefilled syringe before injecting it. Check that the expiration date has not passed and that the liquid is clear and colorless or slightly yellow or brown. The liquid should not contain visible particles. Do not use a dosing pen if it is expired, appears damaged, or if the liquid is cloudy, discolored, or contains particles.

Zilucoplan controls MG but does not cure it. Continue to use zilucoplan even if you feel well. Do not stop using zilucoplan without talking to your doctor.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with zilucoplan injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

What should I know about STORAGE and DISPOSAL of this medication?

Zilucoplan prefilled syringes can be stored at room temperature in their original container protected from light for up to 3 months or can be stored in their original container in the refrigerator until the date on the carton. If storing syringes at room temperature, do not put them back in the refrigerator, and throw them away if not used within the 3 months of removal from the refrigerator or if the expiration date is reached, whichever is first. Make sure you write the date that you removed them from the refrigerator on the outside of the box. Store your medication only as directed. Make sure you understand how to store your medication properly.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. https://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.

See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
