About USTEKINUMAB-AAUZ

What is this medication? Ustekinumab-aauz is a prescription biologic medication used to treat several chronic inflammatory conditions. It is classified as a biosimilar, which means it is highly similar to an original biological product already approved by the FDA. This medication is primarily used for adults and children with moderate to severe plaque psoriasis who may benefit from systemic therapy or phototherapy. It is also indicated for the treatment of active psoriatic arthritis in adults to help manage joint swelling and improve physical movement.

Beyond skin and joint issues, this medication is also prescribed for adults living with moderate to severe Crohn's disease or ulcerative colitis. It functions by inhibiting two specific proteins, interleukin-12 and interleukin-23, which are involved in the body's inflammatory and immune responses. By interfering with these pathways, the drug helps to decrease inflammation in the intestines and on the skin surface. The treatment typically begins with an intravenous infusion and continues with regular subcutaneous injections.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
