Occupational Airborne Contact Dermatitis From Proton Pump Inhibitors.

Few published reports have described occupational contact dermatitis from proton pump inhibitor (PPI) exposure in the literature. We present an additional case of a 58-year-old male pharmaceutical worker with an occupational airborne allergic contact dermatitis to PPIs confirmed by patch testing. This is a novel report of workplace exposure to dexlansoprazole and esomeprazole PPIs with resultant clinical contact allergy and relevant positive patch test results to these 2 agents. A literature review of all previously reported cases of occupational contact dermatitis to PPI is summarized. The case also emphasizes the importance of even minute exposures when considering workplace accommodation.
