Oclacitinib was approved in the United States 10 years ago for the management of atopic dermatitis (AD) and allergic skin disease in dogs. Many studies and case reports have been published in the past 10 years on the efficacy and safety of this medication, both at labeled doses to treat allergic dogs and off label to treat other diseases and given to other species. Concerns and confusion have occurred for both clinicians and owners regarding the long-term safety of this drug. The purpose of this review is to present the current knowledge on the efficacy, speed of action, effects on the immune system, and clinical safety of oclacitinib, based on evidence and published literature. We also aim to summarize the lessons learned in the past 10 years and to propose directions for the future.
