Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of infliximab injection for the treatment of Crohn disease or ulcerative colitis in children 6 years of age and older. However, safety and efficacy have not been established in children younger than 6 years of age.
Appropriate studies have not been performed on the relationship of age to the effects of infliximab injection in children with plaque psoriasis. Safety and efficacy have not been established.
Appropriate studies performed to date have demonstrated that infliximab injection is not helpful in children with juvenile rheumatoid arthritis. Efficacy has not been established.
