A nurse or other trained health professional will give you or your child this medicine. This medicine is given as a shot under your skin or into a vein.

If this medicine is given through a vein in your arm, it must be injected by your doctor slowly and your IV tube will need to stay in place for 30 minutes. You will receive this medicine again at 2 weeks and 4 weeks after your first dose and then every 4 weeks after.

Abatacept may be also given as a shot under your skin. It may sometimes be given at home to patients who do not need to be in the hospital. If you or your child are using this medicine at home, your doctor or nurse will teach you how to prepare and inject the medicine. Be sure that you understand exactly how to use the medicine.

This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

If you use this medicine at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself or your child a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems.

This medicine is available in 3 forms: a vial (glass container), a prefilled syringe, or a ClickJect™ autoinjector. The prefilled syringe and ClickJect™ autoinjector are the dosage forms you can use at home.

Check the liquid in the prefilled syringe or ClickJect™ autoinjector. It should be clear and colorless or slightly yellow. Do not use it if it is cloudy, discolored, or if you see particles in it. Do not use the prefilled syringe or ClickJect™ autoinjector if it looks cracked or broken.

Allow 30 minutes for the syringe to warm up to room temperature. Do not warm this medicine in any other way.

Do not remove the needle cover on the prefilled syringe or the autoinjector cap while allowing the medicine to reach room temperature. Remove only if ready to use.

Check that the amount of liquid in the prefilled syringe falls at or just above the fill line. If the syringe does not have the right amount of liquid, do not use it.

Do not inject into skin areas that are red, bruised, tender, scaly, or hard, or have scars or stretch marks.
