What is Stelara?
Stelara is a prescription biologic medication used to treat autoimmune and inflammatory conditions such as plaque psoriasis, psoriatic arthritis, Crohn’s disease, and ulcerative colitis.
It works by targeting specific proteins in the immune system that cause inflammation, helping reduce symptoms and improve quality of life.
How Stelara Works
Stelara is a monoclonal antibody that blocks interleukin-12 (IL-12) and interleukin-23 (IL-23)—two proteins involved in inflammation.
By doing this, it helps:
- Reduce immune system overactivity
- Decrease inflammation in the body
- Improve skin lesions and joint pain
- Support remission in digestive conditions

- Moderate to severe plaque psoriasis
- Psoriatic arthritis
