Baricitinib 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. The most common serious infections include pneumonia, shingles, and urinary tract infections. The risk for infections may be higher if you also take other drugs that suppress the immune system (such as methotrexate, corticosteroids). Tell your doctor right away if you have any signs of infection (such as a sore throat that doesn't go away, fever, chills, cough, painful/frequent urination, non-healing skin sores).
You should have a tuberculosis (TB) skin test before and during treatment with this medication. Tell your doctor if you have been near someone with tuberculosis or have lived or traveled in areas where certain fungal infections (such as coccidioidomycosis, histoplasmosis) are common. These areas include the Ohio and Mississippi River valleys and the southwestern United States.
Though it is very unlikely to occur, there may be a risk of developing cancer (such as lymphoma, skin cancer) with this medication. Tell your doctor right away if you develop symptoms such as fever that doesn't go away, unusual lumps/growths, unexplained weight loss, night sweats, change in appearance or size of moles, or unusual skin changes.
Baricitinib may rarely cause serious blood clots to form in the legs or lungs. Tell your doctor if you have a history of blood clots (such as deep vein thrombosis, pulmonary embolism). Get medical help right away if you develop symptoms of a blood clot, including shortness of breath/rapid breathing, chest pain, or pain/swelling/warmth in the groin/calf.
Baricitinib is used to treat rheumatoid arthritis. It helps decrease pain, tenderness, and swelling in the joints.
