Description
Abatacept injection is used alone or together with other medicines to treat moderate to severe active rheumatoid arthritis. Abatacept helps keep joint damage from getting worse after other medicines have been used and did not work well.
Abatacept injection is also used alone or together with methotrexate to treat moderate to severe active polyarticular juvenile idiopathic arthritis (pJIA).
Abatacept injection is also used alone or together with other medicines to treat active psoriatic arthritis (PsA), which is a type of arthritis that causes pain and swelling in the joints along with patches of scaly skin on some areas of the body.
Abatacept injection is also used together with other medicines (eg, calcineurin inhibitor, methotrexate) to prevent acute graft-versus-host disease (aGVHD) in patients who will undergo hematopoietic stem cell transplantation (HSCT) from a matched or 1 allele-mismatched unrelated donor.

Before Using

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of abatacept injection in children 2 years of age and older to treat pJIA, to treat PsA, and to prevent aGVHD.

Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of abatacept injection in the elderly.
