What Stelara treats.
- Crohn’s disease
- Ulcerative colitis
- Plaque psoriasis (moderate to severe)
- Psoriatic arthritis
The mechanism.
Stelara (ustekinumab) blocks interleukin-12 and interleukin-23, two cytokines central to chronic inflammation in IBD and psoriasis. By interrupting these signaling pathways, Stelara reduces inflammation in both the gut and skin.
Your Stelara infusion experience.
Initial Stelara dose is given as a weight-based IV infusion over about 1 hour. Subsequent maintenance doses are usually subcutaneous self-injections every 8 weeks at home, though some patients continue with IV. The IV induction is typically done at our infusion center.
Insurance & out-of-pocket cost.
Stelara is covered by most commercial insurance and Medicare Part B when prescribed by your physician for an FDA-approved indication. We verify your benefits before your first infusion and handle prior authorization on your behalf. Most commercially insured patients pay only their standard specialty copay — typically $20–$100 per visit. Manufacturer copay assistance programs may further reduce your cost.
