7 DRUG INTERACTIONS Abatacept: Increased risk of serious infection ( 5.1 , 5.11 , 7.2 ) Anakinra: Increased risk of serious infection ( 5.1 , 5.7 , 7.2 ) Live vaccines: Avoid use with YUFLYMA ( 5.10 , 7.3 ) 7.1 Methotrexate Adalimumab has been studied in rheumatoid arthritis (RA) patients taking concomitant methotrexate (MTX). Although MTX reduced the apparent clearance of adalimumab, the data do not suggest the need for dose adjustment of either YUFLYMA or MTX [see Clinical Pharmacology ( 12.3 )] . It is possible for products that antagonize cytokine activity, such as adalimumab products, to influence the formation of CYP450 enzymes.
