Cimzia Overview

Cimzia belongs to a group of drugs called tumor necrosis factor (TNF) blockers. TNF is a natural substance in the body that can cause inflammation. Cimzia binds to TNF to decrease inflammation and to relieve the signs and symptoms of Crohn's disease, RA, PsA, and ankylosing spondylitis.

Cimzia FDA Warning



Patients treated with this medication are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Cimzia should be discontinued if a patient develops a serious infection or sepsis.

Reported infections include:

  • Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before Cimzia use and during therapy. Treatment for latent infection should be initiated prior to Cimzia  use.
  • Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness.
  • Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria.

The risks and benefits of treatment with Cimzia  should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.

Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with Cimzia, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. 


Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, of which Cimzia is a member. Cimzia is not indicated for use in pediatric patients.
