Stelara contains the active substance ‘ustekinumab’, a monoclonal antibody. Monoclonal antibodies are proteins that recognise and bind specifically to certain proteins in the body.
Stelara belongs to a group of medicines called ‘immunosuppressants’. These medicines work by weakening part of the immune system.
Stelara is used to treat the following inflammatory diseases:
Plaque psoriasis
Plaque psoriasis is a skin condition that causes inflammation affecting the skin and nails. Stelara will reduce the inflammation and other signs of the disease.
Stelara is used in adults with moderate to severe plaque psoriasis, who cannot use ciclosporin, methotrexate or phototherapy, or where these treatments did not work.
Stelara is used in children and adolescents aged 6 years and older with moderate to severe plaque psoriasis who are unable to tolerate phototherapy or other systemic therapies or where these treatments did not work.
Psoriatic arthritis
Psoriatic arthritis is an inflammatory disease of the joints, usually accompanied by psoriasis. If you have active psoriatic arthritis you will first be given other medicines. If you do not respond well enough to these medicines, you may be given Stelara to:
Crohn’s disease
Crohn’s disease is an inflammatory disease of the bowel. If you have Crohn’s disease you will first be given other medicines. If you do not respond well enough or are intolerant to these medicines, you may be given Stelara to reduce the signs and symptoms of your disease.
Ulcerative colitis
Ulcerative colitis is an inflammatory disease of the bowel. If you have ulcerative colitis you will first be given other medicines. If you do not respond well enough or are intolerant to these medicines, you may be given Stelara to reduce the signs and symptoms of your disease.
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using Stelara.
Talk to your doctor or pharmacist before using Stelara. Your doctor will check how well you are before each treatment. Make sure you tell your doctor about any illness you have before each treatment. Also tell your doctor if you have recently been near anyone who might have tuberculosis. Your doctor will examine you and do a test for tuberculosis, before you have Stelara. If your doctor thinks you are at risk of tuberculosis, you may be given medicines to treat it.
Stelara can cause serious side effects, including allergic reactions and infections. You must look out for certain signs of illness while you are taking Stelara. See ‘Serious side effects’ in section 4 for a full list of these side effects.

At the start of treatment, your healthcare provider will assist you with your first injection. However, you and your doctor may decide that you may inject Stelara yourself. If this happens, you will get training on how to inject Stelara. Talk to your doctor if you have any questions about giving yourself an injection.
Take the vial(s) out of the refrigerator. Let the vial stand for about half an hour. This will let the liquid come to a comfortable temperature for injection (room temperature).
Check the vial(s) to make sure:
Children with paediatric psoriasis weighing less than 60 kg need a dose lower than 45 mg. Make sure you know the proper amount (volume) to remove from the vial and type of syringe needed for dosing. If you don’t know the amount or type of syringe needed, contact your healthcare provider for further instruction.
Get everything together that you need and lay out on a clean surface. This includes a syringe, needle, antiseptic wipes, a cotton ball or gauze, and a sharps container (see Figure 1).
