Medically reviewed by Philip Thornton, DipPharm. Last updated on Mar 7, 2023.

Note: This document contains side effect information about infliximab. Some dosage forms listed on this page may not apply to the brand name Avsola.

Applies to infliximab: intravenous powder for solution.


Intravenous route (Powder for Solution)

Increased risk of serious infections leading to hospitalization or death, including TB, bacterial sepsis, invasive fungal infections (such as histoplasmosis) and infections due to other opportunistic pathogens. Discontinue infliximab-dyyb if a patient develops a serious infection. Perform test for latent TB; if positive, start treatment for TB prior to starting infliximab-dyyb. Monitor all patients for active TB during treatment, even if initial latent TB test is negative. Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with tumor necrosis factor (TNF) blockers, including infliximab. Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers including infliximab products. Almost all had received azathioprine or 6-mercaptopurine concomitantly with a TNF-blocker at or prior to diagnosis. The majority of reported cases have occurred in patients with Crohn’s disease or ulcerative colitis, most of whom were adolescent or young adult males.
