Biosimilar knowledge and viewpoints among Brazilian inflammatory bowel disease patients.

Brazilian patients reported higher rates of misconceptions regarding biosimilars than non-Brazilian IBD patients. Although patients still worry about different aspects regarding biosimilars, they also tend to be confident that biosimilars will have an impact on the management of their disease. With the recent approval of many biosimilars in Brazil and the imminent widespread use of these drugs, our data raise awareness for the need of providing patient education to prevent negative expectations toward switching to biosimilars.
