Special notes

Secukinumab has the potential to reactivate latent TB (begin TB treatment before starting).
Patients with suspected latent or active TB should be treated in consultation with an Infectious Diseases physician.

Secukinumab may increase the risk of infection. Treatment should not be initiated in patients with clinically significant active infection until the infection resolves or is adequately treated.


New cases and exacerbations of Crohn disease and ulcerative colitis have occurred in patients being treated with secukinumab.
Patients treated with secukinumab should be monitored for signs and symptoms of inflammatory bowel disease.


Live vaccines should not be given concurrently with secukinumab.
