How does this medication work? What will it do for me?
Sarilumab belongs to the class of medications called biological response modifiers. It is used to treat moderate-to-severe rheumatoid arthritis (RA) for people for whom other disease-modifying anti-rheumatic drugs have not provided enough benefit or for whom the effects are not tolerable.
Sarilumab works by blocking a protein called Interleukin-6 (IL-6), which is found at high levels in people with rheumatoid arthritis. By blocking IL-6, this medication can reduce inflammation in the affected joints.

Are there any other precautions or warnings for this medication?
Bleeding: Sarilumab may cause a reduced number of platelets in the blood, which can make it difficult to stop cuts from bleeding. If you notice any signs of bleeding, such as frequent nosebleeds, unexplained bruising, or black and tarry stools, notify your doctor as soon as possible. Your doctor will order routine blood tests to make sure potential problems are caught early.
Cholesterol: Some people experience increased levels of cholesterol in the blood when they use sarilumab. If you have high cholesterol levels, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Gastrointestinal perforation: There have been rare reports of gastrointestinal perforation occurring with the use of sarilumab. A gastrointestinal perforation is a hole that forms through a wall in the digestive tract. If you have a condition that increases the risk of gastrointestinal perforation, such as diverticulitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infections: This medication can increase the risk of developing an infection, including serious infections such as sepsis (blood infection), pneumonia, and tuberculosis. Before starting treatment with sarilumab, your doctor may test to see if you have tuberculosis. If you notice signs of an infection such as fever, chills, pain, swelling, coughing, or pus, contact your doctor as soon as possible. This medication should also not be started while you have an active infection.
Tell your doctor if you have a history of infections that keep coming back, or other conditions that might increase your risk of infections (e.g., diabetes), or if you have visited or lived in areas where there is a greater risk of certain kinds of fungal infection (e.g., blastomycosis). While you are taking sarilumab, your doctor will monitor you for signs of infection.
Kidney function: The safety and effectiveness of using this medication have not been determined for people with reduced kidney function. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: People taking sarilumab may have changes in liver function that produce abnormal liver test results. Your doctor will recommend regular liver tests while you are taking this medication. If you have severe changes in liver function, your doctor may recommend that you take a lower dose of this medication or stop taking it altogether. This medication is generally not recommended for people with reduced liver function.
