Precautions

Before using abatacept, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: cancer, chronic obstructive pulmonary disease-COPD, current/recent/returning infection (such as tuberculosis, hepatitis), immune system disorder (such as HIV infection, bone marrow disorder).

Abatacept can make you more likely to get infections or may make current infections worse. Stay away from anyone who has an infection that may easily spread (such as chickenpox, COVID-19, measles, flu). Talk to your doctor if you have been exposed to an infection or for more details.

Tell your health care professional that you are using abatacept before having any immunizations/vaccinations. Certain types of vaccines (live vaccines) should not be given during or within 3 months after the last dose of this medication. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).

Children using this medication should have all recommended vaccinations before starting treatment with abatacept. Ask the child's doctor for details.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

It is unknown if this medication passes into breast milk. Consult your doctor before breastfeeding.

Side Effects

Headache, nausea, or cold symptoms such as stuffy head/nose may occur. Pain, irritation, or swelling at/near the injection site may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Because abatacept works by weakening the immune system, it may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as sore throat that doesn't go away, fever, chills, cough).

Rarely, patients using abatacept have developed cancer (such as lymphoma, lung/skin cancer). Tell your doctor right away if you develop symptoms such as unusual lumps/growths/skin changes, swollen glands, night sweats, unexplained weight loss, shortness of breath, wheezing.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
