Ustekinumab belongs to the class of medications called selective immunomodulating agents, also known as biologics. It is used to treat chronic, moderate-to-severe plaque psoriasis for adults who are candidates for phototherapy or systemic therapy. It is also used for adolescents 12 to 17 years of age who can’t tolerate other therapies, or whose symptoms aren’t controlled by other therapies. It may be used alone or with methotrexate to treat to treat psoriatic arthritis.
Ustekinumab is also used to treat adults with moderately to severely active Crohn’s disease who can’t tolerate other medications, or whose symptoms aren’t adequately controlled by other medications.
Ustekinumab works by blocking the action of 2 proteins in the body that are part of the immune system. This decreases the activity of parts of the immune system that are believed to be involved in psoriasis and Crohn’s disease.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Each mL of sterile solution contains 90 mg of ustekinumab. It is available as a pre-filled syringe containing 45 mg (0.5 mL) or 90 mg (1.0 mL) of ustekinumab. Nonmedicinal ingredients: L-histidine, L-histidine monohydrochloride monohydrate, polysorbate 80, sucrose, and water for injection.

To treat adults with either plaque psoriasis or psoriatic arthritis, the usual dose is 45 mg injected under the skin. The dose is repeated in 4 weeks, and then every 12 weeks thereafter. For people who weigh more than 100 kg, a dose of 90 mg may be used. When treating plaque psoriasis, some people may need to receive this medication every 8 weeks. The dose may be injected on top of the thigh or around the abdomen (about 2 inches away from the belly button).
For treating adolescents 12 to 17 years of age with plaque psoriasis, the dose is based on body weight.
For the treatment of Crohn’s disease, the first dose is given as an intravenous (into a vein) infusion and the dose is based on body weight. The dose is repeated as an injection under the skin 8 weeks after the first dose. The usual maintenance dose is 90 mg every 8 weeks.
Most people using this medication can be trained by a health care professional to give themselves the injection. Ustekinumab is used with the guidance and supervision of a doctor. Your doctor or nurse will assist you in the preparation and injection of your first dose (or first few doses). Do not attempt to inject this medication on your own until you completely understand how to inject a dose.
Follow the instructions from your doctor or pharmacist when administering the medication. The solution should be colourless or slightly yellow and may contain a few small clear or white particles of protein. Do not use the injection if it appears cloudy or discoloured, or if you see other particles floating in it. After taking the medication out of the refrigerator, preparing the syringe, and choosing the injection site, inject the dose under the skin as instructed by your health care provider.
Use a different site for each injection to decrease the risk of skin irritation. Dispose of your used needles in an appropriate sharps container.

Health Canada has issued new restrictions concerning the use of Stelara® (ustekinumab). To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
Allergic reaction: In rare cases, some people may develop a serious allergic reaction to this medication. Signs of an allergic reaction include a severe rash, hives, swollen face or throat, or difficulty breathing. If these occur, seek immediate medical attention.
Allergy shots: This medication may affect allergy shots. If you are receiving or have received allergy shots, especially for severe allergic reactions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Immune system and infections: Ustekinumab may lower your ability to fight infections and may increase the risk of infections and reactivate inactive infections. Your doctor may test for tuberculosis before starting this medication.
Your doctor will do regular tests of immune system function while you are using this medication. If you develop a severe infection, contact your doctor as soon as possible.
Latex: The needle cover on the pre-filled syringe contains dry natural rubber (a form of latex). If you are allergic to latex, talk to your doctor before using the pre-filled syringe.
Malignancies (cancer): Ustekinumab may increase the risk of cancer. If you have cancer or have had cancer in the past, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Reversible posterior leukoencephalopathy syndrome (RPLS): This is a rare disease of the brain that may occur when using medications like ustekinumab. If you have had a previous episode of RPLS, ustekinumab may not be an appropriate medication for you. Make sure your doctor knows you have experienced this before. If you experience signs and symptoms of RPLS, such as headache, seizures, change in awareness or consciousness or vision changes, contact your doctor immediately.
Serious infections: Ustekinumab can affect the way your body’s natural defences work to fight infection. This makes the body more likely to develop infections due to bacteria, viruses, and fungi. This effect is increased if you are taking ustekinumab with other medications that reduce the body’s ability to fight infection. For some people, these infections have been fatal. If you have a history of chronic or frequent infections, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Stop taking the medication and tell your doctor right away if you notice symptoms of a serious infection, such as fever, chills, headache, flu-like symptoms, feeling tired, cough, blood in the sputum, shortness of breath, night sweats, weight loss, nausea, vomiting, diarrhea, frequency or burning while passing urine, redness or swelling of skin or joint, cold sores, tooth pain, or new or worsening pain in any part of the body.
If you have an active infection, you should not use this medication until the infection resolves.
Serious skin conditions: There have been reports of rare serious skin conditions (exfoliative dermatitis and erythrodermic psoriasis) in people receiving ustekinumab. If you experience redness and shedding of skin over most of the entire area of the body, contact your doctor immediately.
Tuberculosis: Some people who have had tuberculosis (a lung infection) in the past have had this infection return when they are using ustekinumab. If you have a history of tuberculosis, or have come into recent contact with someone who has tuberculosis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vaccinations: People taking this medication should not receive certain vaccines. Talk to your doctor about whether any vaccines you are scheduled to take may be used with this medication.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while using this medication, contact your doctor immediately.
