Background: Janus kinase (JAK) inhibitors represent a novel class of oral therapies showing efficacy in treating ulcerative colitis (UC) and Crohn’s disease (CD), challenging conventional treatment paradigms. Summary: This review provides an overview of the potential novel uses of JAK inhibitors, focusing on their current approved indications and exploring possibilities beyond these indications. Tofacitinib and filgotinib are approved for UC, while upadacitinib is approved for both UC and CD. Additionally, their potential in acute severe UC, as steroid alternatives, and in managing fistulizing CD or extraintestinal manifestations are discussed. Key Message: JAK inhibitors play an important role in IBD (inflammatory bowel disease) treatment; however, clinicians must balance their promising efficacy with safety concerns. Individualized care and vigilance are essential for optimizing therapeutic benefits while mitigating potential adverse effects. Further research is necessary to clarify their efficacy, safety, and potential applications.
