Use of methotrexate in children.

Methotrexate continues to be the safest and most efficacious second-line drug for the treatment of JRA. In addition, it is useful in other inflammatory conditions in children. Careful education is necessary, particularly with regard to the importance of laboratory tests and the avoidance of comorbidity such as pregnancy and alcohol-induced liver injury. Health care providers should be comfortable discussing these issues with children and adolescents.
