Cimzia Side Effects

Cimzia (certolizumab) reduces the effects of a substance in the body that can cause inflammation.

Cimzia is used to treat the symptoms of Crohn’s disease after other drugs have been tried without successful treatment of symptoms. Cimzia is also used to treat moderate to severe rheumatoid arthritis in adults.

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

You should not receive Cimzia if you have active but untreated tuberculosis. Tell your doctor if you have ever had tuberculosis, if anyone in your household has tuberculosis, or if you have recently traveled to an area where tuberculosis is common. Some people using Cimzia have developed a rare fast-growing type of lymphoma (cancer). This condition affects the liver, spleen, and bone marrow, and it can be fatal. This has occurred mainly in teenagers and young adults using Cimzia or similar medicines to treat Crohn’s disease or ulcerative colitis.

However, people with autoimmune disorders (including rheumatoid arthritis, Crohn’s disease, ankylosing spondylitis, and psoriasis) may have a higher risk of lymphoma. Talk to your doctor about your individual risk.

To make sure you can safely use Cimzia, tell your doctor if you have any of these other conditions:

  • an active or recent infection;
  • signs of infection such as fever, chills, cough, or flu symptoms;
  • open sores or skin wounds;
  • lupus;
  • diabetes;
  • HIV or AIDS;
  • hepatitis┬áB (or if you are a carrier of the virus);
  • a history of cancer;
  • epilepsy or seizure disorder;
  • congestive heart failure;
  • a disease that affects the nerves or muscles, such as multiple sclerosis, myasthenia gravis, Guillain-Barre syndrome;
  • if you have recently been vaccinated with BCG (Bacille Calmette-Guerin); or
  • if you are scheduled to receive any vaccines.
