What is Skyrizi?

Skyrizi (risankizumab) is a medication used to treat adults with certain types of plaque psoriasis, psoriatic arthritis, and Crohn’s disease, which are all autoimmune disorders. Skyrizi works by targeting a specific protein in the immune system called interleukin-23 (IL-23), which is responsible for causing inflammation in these conditions. Skyrizi helps reduce inflammation, which improves the symptoms of these conditions, by attaching to and blocking IL-23.

Skyrizi is a monoclonal antibody that belongs to a class of medications called interleukin-23 antagonists. Skyrizi is given as a subcutaneous injection for plaque psoriasis and psoriatic arthritis, and for Crohn’s disease, it is given as an intravenous infusion for the induction period, then as a subcutaneous injection for maintenance dosing.

Who can use Skyrizi?

Skyrizi is FDA approved to treat:

• Plaque Psoriasis moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.
• Psoriatic Arthritis active psoriatic arthritis in adults.
• Crohn’s Disease moderately to severely active Crohn's disease in adults.
