Why is this medication prescribed?
Risankizumab-rzaa injection is used to treat moderate to severe plaque psoriasis (a skin disease in which red, scaly patches form on some areas of the body) in adults whose psoriasis is too severe to be treated by topical medications alone. Risankizumab-rzaa is in a class of medications called monoclonal antibodies. It works by stopping the action of certain cells in the body that cause the symptoms of psoriasis.
How should this medicine be used?
Risankizumab-rzaa comes as a solution in a prefilled syringe to inject subcutaneously (under the skin). It is usually given as two injections for the first dose, followed by two injections 4 weeks after the first dose, and then two injections every 12 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use risankizumab-rzaa injection exactly as directed. Do not inject more or less of it or inject it more often than prescribed by your doctor.
You may receive your first dose of risankizumab-rzaa injection in your doctor's office. After your first dose, your doctor may allow you or a caregiver to perform the injections at home. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it.
You can inject risankizumab-rzaa injection anywhere on the 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.
Do not shake a syringe that contains risankizumab-rzaa.
If you are using a prefilled syringe that has been refrigerated, place the syringe on a flat surface without removing the needle cap and allow it warm to room temperature for 15 to 30 minutes before you are ready to inject the medication.
Always look at risankizumab-rzaa solution before injecting it. Check that the expiration date has not passed and that the liquid is colorless to slightly yellow and clear. The liquid should not contain visible particles. Do not use a syringe if it is cracked or broken, if it has been dropped, if it is expired, or if the liquid is cloudy or contains large or colored particles.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with risankizumab-rzaa injection. Read the information carefully and ask your doctor or pharmacist if you have any questions.

- you should know that risankizumab-rzaa injection may decrease your ability to fight infection from bacteria, viruses, and fungi and increase the risk that you will get a serious or life-threatening infection. Tell your doctor if you often get any type of infection or if you have or think you may have any type of infection now. This includes minor infections (such as open cuts or sores), infections that come and go (such as herpes or cold sores), and chronic infections that do not go away. If you experience any of the following symptoms during or shortly after your treatment with risankizumab-rzaa injection, call your doctor immediately: fever, sweats, or chills, muscle aches, shortness of breath, warm, red, or painful skin or sores on your body, weight loss, diarrhea, stomach pain, frequent, urgent, or painful urination, or other signs of infection.
- you should know that using risankizumab-rzaa injection increases the risk that you will develop tuberculosis (TB; a serious lung infection), especially if you are already infected with tuberculosis but do not have any symptoms of the disease. Tell your doctor if you have or have ever had TB, if you have lived in a country where TB is common, or if you have been around someone who has TB. Your doctor will perform a skin test to see if you have an inactive TB infection. If necessary, your doctor will give you medication to treat this infection before you start using risankizumab-rzaa injection. If you have any of the following symptoms of TB, or if you develop any of these symptoms during your treatment, call your doctor immediately: cough, chest pain, coughing up blood or mucus, weakness or tiredness, weight loss, loss of appetite, chills, fever, or night sweats.

Unless your doctor tells you otherwise, continue your normal diet.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store risankizumab-rzaa injection in the refrigerator but do not freeze.
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. http://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. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What other information should I know?
