Sarilumab Injection

Sarilumab injection may decrease your ability to fight infection and increase the risk that you will get a serious infection, including severe fungal, bacterial, or viral infections that spread throughout the body. These infections may need to be treated in a hospital and may cause death. Tell your doctor if you often get any type of infection or if you think you may have any type of infection now. This includes minor infections (such as open cuts or sores), infections that come and go (such as cold sores), and chronic infections that do not go away. Also tell your doctor if you have or have ever had diabetes, human immunodeficiency virus (HIV), acquired immunodeficiency syndrome (AIDS), or any other condition that affects your immune system. You should also tell your doctor if you live, have ever lived, of if you have traveled to areas such as the Ohio or Mississippi river valleys where severe fungal infections are more common. Ask your doctor if you are not sure if these infections are common in your area. Tell your doctor if you are taking medications that decrease the activity of the immune system such as the following: abatacept (Orencia); adalimumab (Humira); anakinra (Kineret); certolizumab pegol (Cimzia); etanercept (Enbrel); golimumab (Simponi); infliximab (Remicade); methotrexate (Otrexup, Rasuvo, Trexall); rituximab (Rituxan); steroids including dexamethasone, methylprednisolone (A-Methapred, Medrol, Solu-Medrol), prednisolone (Orapred, Pediapred), and prednisone (Rayos); tocilizumab (Actemra) and tofacitinib (Xeljanz).

Your doctor will monitor you for signs of infection during and after your treatment. If you have any of the following symptoms before you begin your treatment or if you experience any of the following symptoms during or shortly after your treatment, call your doctor immediately: fever; sweating; chills; muscle aches; cough; coughing up bloody mucus; shortness of breath; weight loss; warm, red, or painful skin; sores on the skin; frequent, painful, or burning feeling during urination; diarrhea; stomach pain; or excessive tiredness.

You may already be infected with tuberculosis (TB; a serious lung infection) but not have any symptoms of the disease. In this case, using sarilumab injection may make your infection more serious and cause you to develop symptoms. Your doctor will perform a skin test to see if you have an inactive TB infection before you begin your treatment with sarilumab injection. If necessary, your doctor will give you medication to treat this infection before you start using sarilumab injection. Tell your doctor if you have or have ever had TB, if you have lived in or visited a country where TB is common, or if you have been around someone who has TB. If you have any of the following symptoms of TB, or if you develop any of these symptoms during your treatment, call your doctor immediately: cough, coughing up bloody mucus, weight loss, loss of muscle tone, or fever.
