Patient leaflet - Skyrizi 180 mg solution for injection in cartridge

1. What Skyrizi is and what it is used for

Skyrizi contains the active substance risankizumab.

Skyrizi is used to treat patients 16 years and older with moderate to severe Crohn’s disease and adults with moderate to severe ulcerative colitis.

How Skyrizi works

This medicine works by stopping a protein in the body called ‘IL-23’, which causes inflammation.

Crohn’s disease

Crohn’s disease is an inflammatory disease of the digestive tract. If you have active Crohn’s disease you will first be given other medicines. If these medicines do not work well enough, you will be given Skyrizi to treat your Crohn’s disease.

Ulcerative colitis

Ulcerative colitis is an inflammatory disease of the large bowel. If you have active ulcerative colitis you will first be given other medicines. If these medicines do not work well enough or if you cannot take these medicines, you will be given Skyrizi to treat your ulcerative colitis.

Skyrizi reduces the inflammation and can therefore help to reduce the signs and symptoms of your disease.

2. What you need to know before you use Skyrizi

Do not use Skyrizi

  • if you are allergic to risankizumab or any of the other ingredients of this medicine (listed in section 6).
  • if you have an infection, including active tuberculosis, which your doctor thinks is important.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before and during the use of Skyrizi:

  • if you currently have an infection or if you have an infection that keeps coming back.
  • if you have tuberculosis (TB).
  • if you have recently received or plan to receive an immunisation (vaccine). You should not be given certain types of vaccines while using Skyrizi.

It is important to keep a record of the batch number of your Skyrizi. Every time you get a new pack of Skyrizi, note down the date and the batch number (which is on the packaging after “Lot”) and keep this information in a safe place.

Serious allergic reactions

Skyrizi can cause serious side effects, including serious allergic reactions (‘anaphylaxis’).

Tell your doctor or seek medical help immediately if you notice any signs of an allergic reaction while you are taking Skyrizi such as:

  • difficulty breathing or swallowing
  • swelling of the face, lips, tongue or throat
  • low blood pressure, which can cause dizziness or light-headedness
  • severe itching of the skin, with a red rash or raised bumps

Children and adolescents

Skyrizi is not recommended for children and adolescents under 16 years of age. This is because Skyrizi has not been studied in this age group.

Other medicines and Skyrizi

Tell your doctor, pharmacist or nurse:

  • if you are using, have recently used or might use any other medicines.
  • if you have recently had or are going to have a vaccination. You should not be given certain types of vaccines while using Skyrizi.

If you are not sure, talk to your doctor, pharmacist or nurse before and during the use of Skyrizi.

Pregnancy, contraception and breast-feeding

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine. This is because it is not known how this medicine will affect the baby.

If you are a woman who can become pregnant, you should use contraception while using this medicine and for at least 21 weeks after your last dose of Skyrizi.

If you are breast-feeding or are planning to breast-feed, talk to your doctor before using this medicine.

Driving and using machines

Skyrizi is not likely to affect your driving and use of machines.

Skyrizi contains polysorbate and sodium

This medicine contains 0.24 mg of polysorbate 20 in each 180 mg dose and 0.48 mg of polysorbate 20 in each 360 mg dose. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.

This medicine contains less than 1 mmol sodium (23 mg) per cartridge, that is to say essentially ‘sodium-free’.

3. How to use Skyrizi

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

This medicine is given as an injection under your skin (called a ‘subcutaneous injection’).

Areas to inject

Choose and clean your injection site

Choose from these 3 areas to inject:

  • front of left thigh
  • front of right thigh
  • your belly (abdomen) at least 5 cm from your belly button (navel)

Do not inject into areas of the skin that naturally fold or bulge because the on-body injector could fall off during wear.

Turn the on-body injector over to find both green pull tabs

  • Avoid touching the needle cover (needle inside)

Peel away the large section using the green pull tab to expose the skin adhesive.

Peel away the small section using the green pull tab to expose the skin adhesive. This will remove the clear plastic strip, activating the on-body injector.

The Skyrizi on-body injector must be placed on the skin and injection must be started within 30 minutes after removing the green pull tabs or it will not work. Make sure to proceed to next step without delay.

If the status light flashes red and beeps, the on-body injector is not working properly. Do not continue to use it.

Speak to your doctor, pharmacist or nurse for assistance.

If the on-body injector is attached to your body, carefully remove it from your skin.

Prepare the on-body injector for placement

  • For the belly (abdomen), move and hold the skin to create a firm, flat surface for injection at least 5 cm from your belly button (navel). Make sure to sit up straight to avoid skin folds and bulges
  • You do not need to pull the skin flat for the front of left thigh or right thigh

Make sure to place the on-body injector so that you can see the blue status light.

Place the on-body injector on your skin

  • When the blue light flashes, the on-body injector is ready. Place the on-body injector onto the cleaned skin with the status light visible
  • Do not place the on-body injector on clothes. Only place on bare skin
  • Run your finger around the adhesive material to secure it
  • Do not move or adjust the on- body injector after it has been placed on your skin

Do not continue to use the on- body injector if status light flashes red and beeps. Carefully remove from skin if the status light flashes red. If this happens, speak to your doctor, pharmacist or nurse.

Wait for the injection to finish

  • It may take up to 5 minutes to complete the full dose of medicine. The on-body injector will automatically stop when the injection is finished
  • During the injection, the status light will continue to flash green
  • During the injection, you will hear pumping sounds as the on-body injector continues delivering the medicine
  • During the injection, moderate physical activities can be done, such as walking, reaching and bending
