Read the Medication Guide that comes with RENFLEXIS before you receive the first treatment, and before each time you get a treatment of RENFLEXIS. This Medication Guide does not take the place of talking with your doctor about your medical condition or treatment.

|
What is the most important information I should know about RENFLEXIS?
|
|
RENFLEXIS may cause serious side effects, including:
|
|
1. Risk of infection
|
-
- RENFLEXIS is a medicine that affects your immune system. RENFLEXIS can lower the ability of your immune system to fight infections. Serious infections have happened in patients receiving RENFLEXIS. These infections include 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 RENFLEXIS.
- •
- Your doctor should monitor you closely for signs and symptoms of TB during treatment with RENFLEXIS.
|
|
Before starting RENFLEXIS, tell your doctor if you:
- •
- think you have an infection. You should not start receiving RENFLEXIS if you have any kind of infection.
- •
- are being treated for an infection.
- •
- have signs of an infection, such as a fever, cough, 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 or an immune system problem. People with these conditions have a higher chance for infections.
- •
- have TB, or have been in close contact with someone with TB.
- •
- live or have lived in certain parts of the country (such as the Ohio and Mississippi River valleys) where there is an increased risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis). These infections may develop or become more severe if you receive RENFLEXIS. If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, or blastomycosis is common, ask your doctor.
- •
- have or have had hepatitis B.
- •
- use the medicines KINERET (anakinra), ORENCIA (abatacept), ACTEMRA (tocilizumab), or other medicines called biologics used to treat the same conditions as RENFLEXIS.
|
|
After starting RENFLEXIS, if you have an infection, any sign of an infection including a fever, cough, flu-like symptoms, or have open cuts or sores on your body, call your doctor right away. RENFLEXIS can make you more likely to get infections or make any infection that you have worse.
|
|
2. Risk of Cancer
- •
- There have been cases of unusual cancers in children and teenage patients using tumor necrosis factor (TNF)-blocker medicines, such as RENFLEXIS.
- •
- For children and adults receiving TNF-blocker medicines, including RENFLEXIS, the chances of getting lymphoma or other cancers may increase.
- •
- Some people receiving TNF-blockers, including RENFLEXIS, developed a rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. Most of these people were male teenagers or young men. Also, most people were being treated for Crohn's disease or ulcerative colitis with a TNF-blocker and another medicine called azathioprine or 6-mercaptopurine.
- •
- People who have been treated for rheumatoid arthritis, Crohn's disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and plaque psoriasis for a long time may be more likely to develop lymphoma. This is especially true for people with very active disease.
- •
- Some people treated with infliximab products, such as RENFLEXIS, have developed certain kinds of skin cancer. If any changes in the appearance of your skin or growths on your skin occur during or after your treatment with RENFLEXIS, tell your doctor.
- •
- Patients with Chronic Obstructive Pulmonary Disease (COPD), a specific type of lung disease, may have an increased risk for getting cancer while being treated with RENFLEXIS.
- •
- Some women being treated for rheumatoid arthritis with infliximab products have developed cervical cancer. For women receiving RENFLEXIS, including those over 60 years of age, your doctor may recommend that you continue to be regularly screened for cervical cancer.
- •
- Tell your doctor if you have ever had any type of cancer. Discuss with your doctor any need to adjust medicines you may be taking.
|
|
See the section "What are the possible side effects of RENFLEXIS?" below for more information.
|
|
What is RENFLEXIS?
|
-
- RENFLEXIS is a prescription medicine that is approved for patients with:
- •
- Rheumatoid Arthritis - adults with moderately to severely active rheumatoid arthritis, along with the medicine methotrexate.
- •
- Crohn's Disease - children 6 years and older and adults with Crohn's disease who have not responded well to other medicines.
- •
- Ankylosing Spondylitis
- •
- Psoriatic Arthritis
- •
- Plaque Psoriasis - adult patients with plaque psoriasis that is chronic (does not go away), severe, extensive, and/or disabling.
- •
- Ulcerative Colitis - children 6 years and older and adults with moderately to severely active ulcerative colitis who have not responded well to other medicines.
|
|
RENFLEXIS blocks the action of a protein in your body called tumor necrosis factor-alpha (TNF-alpha). TNF-alpha is made by your body's immune system. People with certain diseases have too much TNF-alpha that can cause the immune system to attack normal healthy parts of the body. RENFLEXIS can block the damage caused by too much TNF-alpha.
|
|
Who should not receive RENFLEXIS?
|
-
- You should not receive RENFLEXIS if you have:
- •
- heart failure, unless your doctor has examined you and decided that you are able to receive RENFLEXIS. Talk to your doctor about your heart failure.
- •
- had an allergic reaction to infliximab products, or any of the other ingredients in RENFLEXIS. See the end of this Medication Guide for a complete list of ingredients in RENFLEXIS.
|
|
What should I tell my doctor before starting treatment with RENFLEXIS?
|
|
Your doctor will assess your health before each treatment.
|
-
- Tell your doctor about all of your medical conditions, including if you:
- •
- have an infection (see "What is the most important information I should know about RENFLEXIS?").
- •
- have other liver problems including liver failure.
- •
- have heart failure or other heart conditions. If you have heart failure, it may get worse while you take RENFLEXIS.
- •
- have or have had any type of cancer.
- •
- have had phototherapy (treatment with ultraviolet light or sunlight along with a medicine to make your skin sensitive to light) for psoriasis. You may have a higher chance of getting skin cancer while receiving RENFLEXIS.
- •
- have COPD. Patients with COPD may have an increased risk of getting cancer while receiving RENFLEXIS.
- •
- have or have had a condition that affects your nervous system such as:
- •
- multiple sclerosis, or Guillain-Barré syndrome, or
- •
- if you experience any numbness or tingling, or
- •
- if you have had a seizure.
- •
- have recently received or are scheduled to receive a vaccine. Adults and children receiving RENFLEXIS should not receive live vaccines (for example, the Bacille Calmette-Guérin [BCG] vaccine) or treatment with a weakened bacteria (such as BCG for bladder cancer). Children should have all of their vaccines brought up to date before starting treatment with RENFLEXIS.
- •
- are pregnant or plan to become pregnant. It is not known if RENFLEXIS harms your unborn baby. RENFLEXIS should be given to a pregnant woman only if clearly needed. Talk to your doctor about stopping RENFLEXIS if you are pregnant or plan to become pregnant.
- •
- are breast-feeding or plan to breast-feed. It is not known whether RENFLEXIS passes into your breast milk. Talk to your doctor about the best way to feed your baby while receiving RENFLEXIS. You should not breast-feed while receiving RENFLEXIS.
|
|
If you have a baby and you were receiving RENFLEXIS during your pregnancy, it is important to tell your baby's doctor and other health care professionals about your RENFLEXIS use so they can decide when your baby should receive any vaccine. Certain vaccinations can cause infections.
|
|
If you received RENFLEXIS while you were pregnant, your baby may be at higher risk for getting an infection. If your baby receives a live vaccine within 6 months after birth, your baby may develop infections with serious complications that can lead to death. This includes live vaccines such as the BCG, rotavirus, or any other live vaccines. For other types of vaccines, talk with your doctor.
|
|
How should I receive RENFLEXIS?

- You will be given RENFLEXIS through a needle placed in a vein (IV or intravenous infusion) in your arm.
- •
- Your doctor may decide to give you medicine before starting the RENFLEXIS infusion to prevent or lessen side effects.
- •
- Only a healthcare professional should prepare the medicine and administer it to you.
