By Bristol-Myers Squibb

What is this medication for?

Abatacept belongs to a group of medications called selective costimulation modulators. It is used to treat adults with moderate-to-severe rheumatoid arthritis or to treat children 6 years of age and older with moderate-to-severe active polyarticular juvenile idiopathic arthritis. Abatacept can be used alone or in combination with a disease-modifying antirheumatic drug (DMARD).

For people with rheumatoid arthritis, the immune system attacks normal tissues in the joints, causing pain, inflammation, and damage. Abatacept works by keeping the immune system from attacking normal tissues.

How should I use this medication?

The recommended dose of abatacept varies according to body weight. It is injected intravenously (into a vein) by a health care professional, usually in a clinical setting such as a hospital. The appropriate dose is usually given once every 2 weeks for the first 3 doses, and then once every 4 weeks thereafter.

For adults with rheumatoid arthritis, abatacept may also be given subcutaneously (under the skin) with or without the initial intravenous dosing by a health care professional. Your doctor will demonstrate how you can do this at home. Dosing for subcutaneous injection is usually once a week.

Abatacept is used with the guidance and supervision of a doctor. Your doctor or nurse will assist you in the preparing and injecting your first dose (or first few doses). Do not attempt to prepare or inject this medication on your own until you completely understand how to mix and inject a dose. If you are having difficulty giving yourself injections, talk to your health care provider.

It is important that this medication be used exactly as prescribed by your doctor. If you miss an appointment to receive abatacept, contact your doctor as soon as possible to reschedule your appointment.
