What is the most important information I should know about CIMZIA?
CIMZIA is a medicine that affects your immune system. CIMZIA can lower the ability of the immune system to fight infections. Serious infections have happened in patients taking CIMZIA, including tuberculosis (TB) and infections caused by viruses, fungi, or bacteria that have spread throughout the body. Some patients have died from these infections.

• Your doctor should test you for TB before starting CIMZIA
• Your doctor should monitor you closely for signs and symptoms of TB during treatment with CIMZIA

Before starting CIMZIA, tell your doctor about all of your medical conditions, including if you:

• Think you have an infection. You should not start taking CIMZIA if you have any kind of infection (See "What is the most important information I should know about CIMZIA?")
• Are being treated for an infection
• Have signs of an infection, such as a fever, cough, or flu-like symptoms
• Have any open cuts or sores on your body
• Get a lot of infections or have infections that keep coming back
• Have diabetes
• Have HIV
• Have TB, or have been in close contact with someone with TB
• Were born in, lived in, or traveled to countries where there is more risk of getting TB. Ask your doctor if you are not sure
• Live or lived in certain parts of country (such as the Ohio and Mississippi River valleys) where there is an increased risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, blastomycosis). These infections may develop or become severe if you take CIMZIA. If you do not know if you have lived in these types of areas, ask your doctor
• Have or have had hepatitis B
• Have or have had any type of cancer
• Have congestive heart failure
• Have seizures, any numbness or tingling, or a disease that affects your nervous system such as multiple sclerosis
• Are scheduled to receive a vaccine. Do not receive a live vaccine while taking CIMZIA
• Are pregnant, planning to become pregnant, or breastfeeding. CIMZIA has not been studied in pregnant or nursing women
• Are allergic to any of the ingredients in CIMZIA
• Are taking any medicines, including prescription and nonprescription medicines, vitamins, and herbal supplements. Your doctor will tell you if it is okay to take your other medicines while taking CIMZIA
• Especially tell your doctor if you take:
  • Kineret^® (anakinra), Orencia^® (abatacept), Rituxan^® (rituximab), Tysabri^® (natalizumab). You have a higher chance for serious infections when taking CIMZIA with these medicines
  • A TNF-blocker: Remicade^® (infliximab), Humira^® (adalimumab), Enbrel^® (etanercept)

How should I use CIMZIA?
CIMZIA is available as a lyophilized powder for reconstitution or in a prefilled syringe. If your doctor prescribes the lyophilized pack, CIMZIA should be injected by a healthcare provider. If your doctor prescribes the prefilled syringe, see the section "Patient Instructions for Use" at the end of the Medication Guide for complete instructions for use. Do not give yourself an injection of CIMZIA unless you have been shown how by your doctor or nurse—or they can train someone you know to help you with your injection. CIMZIA is given by an injection under the skin. Your doctor will tell you how much CIMZIA to inject and how often, based on your condition to be treated. Make sure to keep all of your injection and follow-up appointments with your doctor.

After starting CIMZIA, if you get an infection, any sign of an infection including a fever, cough, or flu-like symptoms, or have open cuts or sores on your body, call your doctor right away. CIMZIA can make you more likely to get infections or make any infection that you may have worse.

What are the possible side effects of CIMZIA?
Serious side effects have happened in patients taking CIMZIA including:

• Serious infections including TB. See "What is the most important information I should know about CIMZIA?"
• Certain types of cancer. There have been cases of certain types of cancer in people taking CIMZIA or other TNF-blockers. People with RA, especially more serious RA, may have a higher chance for getting a kind of cancer called lymphoma
• Heart failure including new heart failure or worsening of heart failure you already have. Symptoms include shortness of breath or swelling of your ankles or feet
• Nervous system problems such as multiple sclerosis, seizures, or inflammation of the nerves of the eyes. Symptoms include dizziness, numbness or tingling, problems with your vision, and weakness in your arms or legs
• Allergic reactions. Signs of an allergic reaction include a skin rash, swollen face, or trouble breathing
• Hepatitis B virus reactivation in patients who carry the virus in their blood. In some cases, patients have died as a result of hepatitis B virus being reactivated. Your doctor should monitor you carefully during treatment with CIMZIA if you carry the hepatitis B virus in your blood. Tell your doctor if you have any of the following symptoms: feel unwell, poor appetite, tiredness (fatigue), fever, skin rash, or joint pain
• Blood problems. Your body may not make enough of the blood cells that help fight infections or help stop bleeding. Symptoms include a fever that doesn't go away, bruising or bleeding very easily, or looking very pale
• Immune reactions including a lupus-like syndrome. Symptoms include shortness of breath, joint pain, or a rash on the cheeks or arms that worsens with sun exposure

Call your doctor right away if you develop any of the above side effects or symptoms.

The most common side effects of CIMZIA are upper respiratory infections (flu, cold), rash, and urinary tract infections (bladder infections).

Injection site reactions happen in some people. Tell your doctor about any side effect that bothers you or does not go away. These are not all of the side effects with CIMZIA. Ask your doctor or pharmacist for more information.
