Stelara (Ustekinumab)

Stelara (Ustekinumab) is a biologic medicine that suppresses the immune system in order to treat psoriatic arthritis and psoriasis.

Stelara works by blocking two signalling proteins called cytokines named interleukin-12 (IL-12) and interleukin-23 (IL-23). These cytokines regulate the body's immune system and are related to its inflammatory response.

Taking Stelara

Stelara is available as a pre-filled syringe that can be administered at home.

Although some patients who take Stelara can feel better quite quickly, in others it can take a little longer. It is important to keep taking this medicine as prescribed by a doctor.
