Ustekinumab (Stelara) is a human interleukin-12 and -23 antagonist with multiple adult and pediatric indications. Stelara was first indicated to treat adults with moderate to severe plaque psoriasis in 2009, and has subsequently received additional U.S. Food and Drug Administration (FDA)-approved indiciations. Stelara is currently approved for the treatment of adult and pediatric patients with moderate to severe plaque psoriasis, active psoriatic arthritis, and moderately to severely active Crohn's disease, along with being approved for use in the treatment of adults with moderately to severely active ulcerative colitis. Most recently, in April 2026, the FDA approved Stelara for the treatment of pediatric patients 2 years and older with moderately to severely active Crohn's disease.

Read on to learn more about Stelara, including its warnings and precautions, dosage and administration information, appearance in clinical practice guidelines, and more.

Consider diagnostic tests for these infections as dictated by clinical circumstances.
  • Tuberculosis (TB): Evaluate patients for TB prior to initiating treatment with Stelara. Initiate treatment of latent TB before administering Stelara.
  • Malignancies: Stelara may increase risk of malignancy. The safety of Stelara in patients with a history of or a known malignancy has not been evaluated.

    • “Biosimilar infliximab, adalimumab, and ustekinumab are effective treatments for patients with moderate-to-severe CD and can be used for de novo induction and maintenance therapy.”
  • Pharmacological Management of Moderate to Severe Ulcerative Colitis
    • American Gastroenterological Association (AGA)
    • November 2024
    • “In adult outpatients with moderate-to-severe UC, the AGA recommends the use of infliximab, golimumab, vedolizumab, tofacitinib, upadacitinib, ustekinumab, ozanimod, etrasimod, risankizumab, and guselkumab, and suggests the use of adalimumab, filgotinib, and mirikizumab over no treatment.”
