BOXED WARNING

  • If ALT elevation > 3 fold ULN occurs, interrupt Arava therapy while investigating the probable cause of the ALT elevation by close observation and additional tests. If likely leflunomide-induced, start cholestyramine washout and monitor liver tests weekly until normalized. If leflunomide-induced liver injury is unlikely because some other probable cause has been found, resumption of Arava therapy may be considered.
