How does ORENCIA work?
ORENCIA keeps the immune system from attacking healthy tissues in the body. The immune system is the body’s defence against attack by, for example, bacteria and viruses. A normal immune system leaves healthy body tissues alone. In people with RA, the immune system attacks normal body tissues. This can cause damage and inflammation, especially in the tissues of your joints.
ORENCIA modifies an important step in this attack. By decreasing the immune system’s attack on normal tissues, ORENCIA can reduce pain, joint inflammation, and damage to your bones and cartilage. ORENCIA may also help you with your daily activities (such as getting dressed, walking and climbing stairs).
