Drug-induced acne is a common side effect to a wide array of pharmacological therapies and is characterized by a monomorphic, papulopustular eruption typically affecting the face, scalp, and the upper thorax. Corticosteroids and Janus kinase inhibitors (JAKi) are commonly used for the treatment of inflammatory bowel disease (IBD) and are known to aggravate a prior tendency to acne or trigger the development of new acneiform eruptions. Recent attention on managing drug-induced acne has been driven by the increasing use of JAKi, an expanding therapeutic class in IBD and several other immune-mediated inflammatory diseases. Both randomized controlled trials and real-world studies have identified acne as one of the most common treatment-emergent adverse events in JAKi. Left untreated, this common skin reaction can significantly impact patient self-esteem and quality of life leading to poor treatment adherence and suboptimal IBD control. This review examines the characteristics of drug-induced acne in IBD treatments, provides a practical guide for gastroenterologists to manage mild to moderate occurrences, and highlights when to seek specialist dermatology advice. Such approaches enable early treatment of a common and often distressing adverse event and optimizes the management of IBD by preventing the premature discontinuation or dose reduction of efficacious IBD drugs.
