Skyrizi Pen is used to treat moderate to severe plaque psoriasis in adults.

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

You may get infections more easily. Call your doctor right away if you have signs of infection such as: fever, chills, sweats, muscle aches, skin sores, stomach pain, diarrhea, burning when you urinate, weight loss, cough, shortness of breath, or a cough with red or pink mucus.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Skyrizi Pen is injected under the skin.

Ask your doctor or pharmacist if you don't understand how to use an injection.

Prepare an injection only when you are ready to give it. You may need to use 2 injections to get your total dose.

Skyrizi Pen should be clear or light-yellow. Call your pharmacist if the medicine looks cloudy, has changed colors, or has particles in it.

Your healthcare provider will show you where to inject Skyrizi Pen. Do not inject into the same place two times in a row. Avoid injecting into skin that is hard, red, bruised, swollen, tender, or affected by psoriasis. Do not inject within 2 inches of your navel (belly button).

You may get infections more easily, even serious infections. You will need frequent medical tests.

Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.

Store Skyrizi Pen in the original carton in a refrigerator and use until expiration date. Protect from light and do not shake or freeze.

Take the medicine out of the refrigerator and let it reach room temperature for 30 to 90 minutes before using. Do not heat the medicine in a microwave or with hot water.

Throw away a prefilled syringe or injection pen after one use, even if there is still medicine left inside.

Throw away any Skyrizi Pen that has been frozen, dropped, or damaged.
