How does Simponi work?

Simponi and Simponi Aria are both medicines known as tumor necrosis factor (TNF) inhibitors. TNF is a protein made by your immune system. In people with certain autoimmune diseases, such as RA, the immune system makes too much TNF. This leads to RA symptoms like joint pain, stiffness, and swelling.1,2

Simponi and Simponi Aria work by targeting and sticking to the extra TNF in your body. This helps reduce RA symptoms and prevent further joint damage.1,2
