What is Renflexis?

See also: Stelara

Renflexis reduces the effects of a substance in the body that can cause inflammation.

Renflexis is used to treat rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, Crohn's disease, and ankylosing spondylitis. This medicine is also used to treat severe or disabling plaque psoriasis.

Renflexis is often used when other medicines have not been effective.

Renflexis may also be used for purposes not listed in this medication guide.

Important Information

Using Renflexis may increase your risk of developing certain types of cancer, including a rare fast-growing type of lymphoma that can be fatal. Ask your doctor about your specific risk.

Renflexis affects your immune system. You may get infections more easily, even serious or fatal infections. Call your doctor if you have a fever, tiredness, flu symptoms, cough, or skin pain.

Before taking this medicine

You should not be treated with Renflexis if you are allergic to it.

Tell your doctor if you have ever had tuberculosis or if anyone in your household has tuberculosis. Also tell your doctor if you have recently traveled. Tuberculosis and some fungal infections are more common in certain parts of the world, and you may have been exposed during travel.

Tell your doctor if you have ever had:

  • heart failure or other heart problems;

  • an active infection (fever, cough, flu symptoms, open sores or skin wounds);

  • diabetes;

  • liver failure, hepatitis B, or other liver problems;

  • chronic obstructive pulmonary disease (COPD);

  • heart problems;

  • cancer;

  • a weak immune system;

  • seizures;

  • numbness or tingling anywhere in your body;

  • a nerve-muscle disorder, such as multiple sclerosis or Guillain-Barré syndrome;

  • phototherapy for psoriasis;

  • vaccination with BCG (Bacille Calmette-Guérin); or

  • if you are scheduled to receive any vaccines.

Make sure your child is current on all vaccines before he or she starts treatment with Renflexis.

Renflexis may cause a rare type of lymphoma (cancer) of the liver, spleen, and bone marrow that can be fatal. This has occurred mainly in teenagers and young men with Crohn's disease or ulcerative colitis. However, anyone with an inflammatory autoimmune disorder may have a higher risk of lymphoma. Talk with your doctor about your own risk.

Renflexis may cause other types of cancer, such as skin cancer or cancer of the cervix. Ask your doctor about this risk.

If you use Renflexis while you are pregnant, make sure any doctor caring for your new baby knows that you used the medicine during pregnancy. Being exposed to this medicine in the womb could affect your baby's vaccination schedule during the first 6 months of life.

You should not breast-feed while you are receiving Renflexis.

Renflexis is not for use in children younger than 6 years old.

How is Renflexis given?

Before you start treatment with Renflexis, your doctor may perform tests to make sure you do not have tuberculosis or other infections.

Renflexis is given as an infusion into a vein. A healthcare provider will give you this injection.

You may be watched closely after receiving Renflexis, to make sure the medicine has not caused any serious side effects.

Renflexis affects your immune system. You may get infections more easily, even serious or fatal infections. Your doctor will need to examine you on a regular basis, and you may need frequent TB tests.

If you need surgery, tell the surgeon ahead of time that you are using Renflexis.

If you've ever had hepatitis B, using Renflexis can cause this virus to become active or get worse. You may need frequent liver function tests while using Renflexis and for several months after you stop.
