Do not receive a "live" vaccine while using abatacept, and for at least 3 months after your treatment ends. The vaccine may not work as well during this time, and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), Bacillus Calmette-GuÃ©rin (BCG), oral polio, rotavirus, smallpox, typhoid, yellow fever, varicella (chickenpox), H1N1 influenza, and nasal flu vaccine.
Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.
There may be other drugs that can interact with abatacept. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
