Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Orencia (abatacept) and Humira (adalimumab) are used to treat autoimmune conditions, but they have some key differences. Orencia is available as an infusion or injection and is used for rheumatoid arthritis (RA), psoriatic arthritis (PsA), and juvenile idiopathic arthritis (JIA), among other conditions. Humira, on the other hand, is also available as an injection and treats a wider range of conditions, including RA, PsA, Crohn's disease, ulcerative colitis, and plaque psoriasis. Orencia is typically given once a week or once a month, while Humira is usually administered every other week. Both medications can increase the risk of infections, but Humira also has a higher risk of causing certain cancers and nervous system effects. Additionally, Orencia can interfere with blood sugar readings in people with diabetes, which is not a concern with Humira.
