The administration route of JAK inhibitors is oral, not a subcutaneous/intravenous injection.
Considering the potential harmful effects of oral steroids, the concomitant use of an oral steroid is not necessary for the treatment of RA using JAK inhibitors, and we should use the lowest possible dose of oral steroids for the shortest time as in the EULAR recommendation.
