Abstract

Interstitial pneumonitis is a well documented, rare complication of methotrexate (MTX). We describe a patient with rheumatoid arthritis (RA) taking MTX for more than 3 years who then developed severe interstitial pneumonitis after a third infliximab infusion. Other similar cases are reviewed. Infliximab may potentiate pulmonary toxicity of MTX.
