The normal dose for the injection is 125 mg, once a week.

Subcutaneous injections (under the skin injections) are easy to do compared to other types of injections. A small needle pokes just under the skin to deliver medicine into the “fatty tissue” below.

The starting dose for intravenous infusions is 500 to 1000 mg, depending on body weight.

Patients receiving infusions are “ramped up” to a regular schedule when they get started. The first dose is administered at week 0. The second dose is given on week 2, and the third dose on week 4.

The “maintenance dose” begins 4 weeks after the third dose and infusions are then given every 4 weeks after that.

It can take about 30 to 60 minutes to receive an infusion at a clinic.

Orencia can make it a bit harder for people to fight off infections.

Patients taking this medicine should call their doctor they have a fever, think they have an infection, or have been prescribed antibiotics to treat an infection.

Patients should coordinate with their doctor to stop treatment before any surgery. It can be re-started once things have healed and there’s no sign of infection.

Patients should discuss all vaccinations with their doctor because some (live vaccines) are not advisable to get while taking Orencia.

It is important to get a TB (tuberculosis) skin test and a chest x-ray before starting Orencia.

Orencia is a newer medication so there is no reliable information about its safety in patients who are pregnant or breastfeeding.

It is recommended to avoid pregnancy or breastfeeding while taking this medication.

In some people with inflammatory arthritis, the body’s immune system becomes confused. It mistakes the cells of the body’s own joints for foreign invaders and attacks them. When the body’s immune system attacks normal body cells by mistake, it is called an autoimmune disease.

Orencia is a synthetic protein called a fusion protein that is a type of modified antibody. It was created by researchers to suppress the body’s immune system.

Orencia works by preventing an important immune system cell, the T-cell, from becoming activated, or turned on. In patients whose T-cells are attacking the body’s own joints by mistake, this effect helps reduce the attack.

Patients can benefit from reduced pain and swelling (inflammation) in the joints, improved day-to-day function, and the prevention of long-term damage.

The immune system is an important system in the body that fights off attacks from dangerous invaders like bacteria and viruses that make people sick.

Because Orencia suppresses the immune system, patients taking the medication will have a slightly harder time fighting off infections. At the same time, Orencia can help to stabilize overactive immune systems in patients whose T-cells are attacking bodily tissues that they shouldn’t.

Orencia’s (abatacept’s) ability to suppress the immune system can make it harder for patients to fight infections. It is important for patients to tell their doctor if they have a fever or infection, or if they think they might have an infection.

• Emphysema (COPD) and Pneumonia: Orencia can worsen symptoms of emphysema (COPD) and make pneumonia worse. Patients who have emphysema or COPD should tell their doctor.
