Abatacept Injection

pronounced as (a ba ta' sept)

Why is this medication prescribed?

Abatacept is used alone or in combination with other medications to reduce the pain, swelling, difficulty with daily activities, and joint damage caused by rheumatoid arthritis (a condition in which the body attacks its own joints causing pain, swelling, and loss of function) in adults who have not been helped by other medications. It is also used alone or in combination with methotrexate (Trexall) to treat polyarticular juvenile idiopathic arthritis (PJIA; a type of childhood arthritis that affects five or more joints during the first six months of the condition, causing pain, swelling, and loss of function) in children 2 years of age or older. Abatacept is also used alone or in combination with other medications to treat psoriatic arthritis (condition that causes joint pain and swelling and scales on the skin) in adults. Abatacept is in a class of medications called selective costimulation modulators (immunomodulators). It works by blocking the activity of T-cells, a type of immune cell in the body that causes swelling and joint damage in people who have arthritis.

How should this medicine be used?

Abatacept comes as a powder to be mixed with sterile water to be given intravenously (into a vein) and as a solution (liquid) in a prefilled syringe or an autoinjector to be given subcutaneously (under the skin). It is usually given by a doctor or nurse in a doctor's office or healthcare facility when given intravenously. It also my be given subcutaneously by a doctor or nurse or you or a caregiver may be told to inject the medication subcutaneously at home. When abatacept is given intravenously to treat rheumatoid arthritis or psoriatic arthritis, it is usually given every 2 weeks for the first 3 doses and then every 4 weeks for as long as treatment continues. When abatacept is given intravenously to treat polyarticular juvenile idiopathic arthritis in children 6 years and older, it is usually given every two weeks for the first two doses and then every four weeks for as long as treatment continues. It will take about 30 minutes for you to receive your entire dose of abatacept intravenously. When abatacept is given subcutaneously to treat rheumatoid arthritis or psoriatic arthritis in adults and polyarticular juvenile idiopathic arthritis in children 2 years and older, it is usually given once weekly.

If you will be injecting abatacept injection by yourself at home or having a friend or relative inject the medication for you, ask your doctor to show you or the person who will be injecting the medication how to inject it. You and the person who will be injecting the medication should also read the manufacturer's written instructions for use that come with the medication.

Before you open the package containing your medication, check to be sure that the expiration date printed on the package has not passed. After you open the package, look closely at the liquid in the syringe. The liquid should be clear or pale yellow and should not contain large, colored particles. Call your pharmacist, if there are any problems with the package or the syringe. Do not inject the medication.

You may inject abatacept injection anywhere on your stomach or thighs except your navel (belly button) and the area 2 inches around it. If someone else will be injecting the medication for you, that person can also inject it into the outer area of your upper arm. Use a different spot for each injection. Do not inject abatacept injection into a spot that is tender, bruised, red, or hard. Also, do not inject into areas with scars or stretch marks.
