Ocular comorbidities are more frequent in patients with severe atopic dermatitis (AD) compared to general population. Dupilumab, a fully human monoclonal antibody that prevents the signaling of interleukin (IL)‐4 and IL‐13, is reported to be efficacious and safe for the treatment of moderate‐to‐severe AD, asthma, and chronic sinusitis. However, conjunctivitis was the most common side effect observed both in clinical trials and real‐life studies in atopic patients. In our experience, among all patients treated with dupilumab from June 2018 to February 2021, we observed a total of 42 cases (10.42%) of conjunctivitis, appearing approximately 13.8 weeks after initiating treatment. Thirty‐five patients (8.68%) developed mild‐to‐moderate conjunctivitis, and 7 (1.74%) severe conjunctivitis. The drug was discontinued in all 7 patients with severe conjunctivitis.
