Purpose of the guideline: IL-6 targeted drugs in the world currently include Siltuximab targeting IL-6, Tocilizumab, Sarilumab and Satralizumab targeting IL-6 receptor, and Janus kinase (JAK) inhibitors. In China, siltuximab, tocilizumab and JAK inhibitors have been marketed. There are few reports on the application of siltuximab in patients with rheumatic diseases. The expert consensus on the off-label administration of JAK inhibitors in the treatment of rheumatic diseases has been published. The off-label administration of tocilizumab in clinical practice of rheumatic diseases is very common and increasing. Therefore, it is necessary to form an expert consensus aiming to provide the reference for rational use of tocilizumab among clinicians and the pharmacovigilance monitoring.
