Description
Meghan McPhie and co-authors report a 2024 case where a skin allergy drug erased patch test results. The patient was a woman in her thirties with eczema and contact allergy. She started upadacitinib, a Janus kinase blocker used for eczema. Patch tests after starting the drug came back negative.
That change raises a practical puzzle for allergy clinics. The drug calms immune pathways that patch tests rely on. A negative test on the drug may hide a real allergy. Whether the drug also treats contact allergy itself is unclear. Doctors may need to test before starting such therapy. The case is a caution for test timing.
