Stelara Side Effects

Stelara (ustekinumab) is an immunosuppressant that reduces the effects of a chemical substance in the body that can cause inflammation.

Stelara is used to treat plaque psoriasis (raised, silvery flaking of the skin) in adults.

You should not use Stelara if you are allergic to ustekinumab or if you have received a BCG (Bacillus Calmette and Guérin) vaccine within the past year (12 months).

BCG vaccine should not be given for at least 1 year after you receive your last dose of Stelara.

Before using Stelara, tell your doctor if you have an active infection, a history of tuberculosis or recurrent infections, high blood pressure, a weak immune system, or if you are receiving phototherapy (light therapy).

Your doctor may perform tests to make sure you do not have tuberculosis or other infections.

Make sure you are current on all vaccines before you start treatment with Stelara.

Stelara can make it easier for you to get sick. Avoid being near people who have colds, the flu, or other contagious illnesses.

Contact your doctor right away if you have signs of infection such as fever, chills, sore throat, flu symptoms, swollen glands, unusual weakness, mouth and throat ulcers, rapid heart rate, rapid and shallow breathing, swelling or redness, pain or burning when you urinate, blood in your urine, severe stomach pain, changes in your bowel habits, cough with yellow or green mucus, stabbing chest pain, or severe headache with confusion, vision problems, or seizure.

Treatment with Stelara may increase your risk of developing cancer. Talk to your doctor about your individual risk.

Get emergency medical help if you have any of these signs of an allergic reaction to Stelara: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

  • signs of infection such as fever, chills, sore throat, flu symptoms, swollen glands, unusual weakness;
