Xeljanz oral Warnings
Tofacitinib may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection (such as fungal infections, bacterial infections including tuberculosis) or make any infection you have worse. The risk for infections may be higher if you also take other drugs that suppress the immune system (such as cyclosporine, tacrolimus).
You should have a tuberculosis (TB) skin test before and during treatment with this medication. Tell your doctor your medical history, especially of past/recent/current infections. You should also tell your doctor if you have lived or traveled in areas where certain fungal infections (such as coccidioidomycosis, histoplasmosis) are common or if you have been near someone with tuberculosis. Areas where these types of fungal infections are commonly found include the Ohio and Mississippi River valleys and the southwestern United States. See Side Effects section for symptoms of infections to watch out for, and tell your doctor right away if you develop any of these symptoms.
Though it is very unlikely to occur, there may be a risk of developing cancer (such as lymphoma, skin cancer) with this medication. Discuss the risks and benefits of treatment with your doctor. Tell your doctor right away if you develop symptoms such as unusual lumps/growths, unexplained weight loss, persistent fever, night sweats, change in appearance or size of moles, or unusual skin changes.
In patients with a kidney transplant who are also taking other drugs that suppress the immune system, there may also be a risk of developing a certain white blood cell disorder (Epstein Barr Virus-associated post-transplant lymphoproliferative disorder) with this medication. Discuss the risks and benefits of treatment with your doctor.
