Before Using This Medicine:

WARNING: PATIENTS WHO USE THIS MEDICINE HAVE AN INCREASED RISK OF DEVELOPING SERIOUS AND SOMETIMES FATAL INFECTIONS such as bacterial, viral, or fungal infections, or tuberculosis (TB). Most patients who developed these infections were taking medicines that weakened their immune systems (eg, methotrexate, corticosteroids). TB may be caused by a new infection or by reactivation of a previous infection. Your doctor will test you for TB and evaluate your risk for developing it. This will occur before, during, and after treatment with this medicine. If you have TB, you should begin to treat it before you begin treatment with this medicine. Tell your doctor if you have a history of persistent or recurring infections. CONTACT YOUR DOCTOR IMMEDIATELY if you develop signs of TB or any other type of infection (eg, persistent cough; muscle weakness; unexplained weight loss; fever, chills, or persistent sore throat; shortness of breath; unusual tiredness; warm, red, or painful skin; sores on your body; increased or painful urination). THIS MEDICINE IS A TNF-BLOCKER. Lymphoma and other types of cancer have been reported in children and teenagers treated with TNF-blockers. This has been fatal in some cases. Talk with your doctor for more information. Some medicines or medical conditions may interact with this medicine. INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. DO NOT TAKE THIS MEDICINE if you are taking cyclophosphamide, abatacept, anakinra, or tocilizumab. ADDITIONAL MONITORING OF YOUR DOSE OR CONDITION may be needed if you are taking corticosteroids (eg, prednisone), insulin or other diabetes medicines (eg, metformin), or methotrexate. Tell your doctor if you are using medicine to treat an infection. DO NOT START OR STOP any medicine without doctor or pharmacist approval. Inform your doctor of any other medical conditions, including any kind of infection; open cuts or sores on your body; flu-like symptoms or other signs of infection (eg, fever; chills; cough; warm, red, or painful skin); numbness or tingling; a disease that affects your nervous system (eg, multiple sclerosis (MS), Guillain-Barre syndrome, seizures); conditions that may increase your risk of infection (eg, diabetes, HIV); allergies, including rubber or latex; pregnancy; or breast-feeding. Tell your doctor if you have a history of persistent or recurring infections, TB or a positive TB skin test, lymphoma or other cancers, liver problems (eg, hepatitis B), liver problems caused by drinking alcohol (alcoholic hepatitis), hepatitis B virus reactivation when taking this medicine or other TNF blockers, congestive heart failure, blood problems (eg, anemia), bone marrow problems, an autoimmune disorder (eg, lupus), immune system problems (eg, weakened immune system), rectalbleeding, shingles (herpes zoster), or Wegener granulomatosis. Tell your doctor if you have ever lived in or traveled to an area where TB is common, or if you live in or have traveled to certain parts of the country (eg, Ohio or Mississippi river valleys, the Southwest) where certain fungal infections (eg, blastomycosis, coccidioidomycosis, histoplasmosis) are common. Check with your doctor if you are not sure if you have lived in or have traveled to an area where these infections are common. Tell your doctor if you have been in close contact with someone who has had TB, if you have recently received a vaccine, or if you are scheduled to have surgery or any kind of vaccination. USE OF THIS MEDICINE IS NOT RECOMMENDED if you have an infection that has spread throughout your entire body (sepsis), or if you have Wegener granulomatosis and are taking a medicine that may weaken the immune system (eg, corticosteroids, methotrexate). Contact your doctor or pharmacist if you have any questions or concerns about using this medicine.
