Post-Hyaluronic Acid Filler Reaction Treated With Abrocitinib: A Case Report.

Post-hyaluronic acid filler nodules are uncommon, unpredictable complications that present a challenge to clinical therapy. We report a case of a female in her fifties who developed edema and nodules 6 weeks after hyaluronic acid (HA) filler injection. After minimal improvement with oral steroids and intralesional hyaluronidase, a trial of oral abrocitinib was initiated, which yielded significant clinical improvement. Thus, abrocitinib may be a novel therapeutic option for delayed-onset nodules following injection of hyaluronic acid. J Drugs Dermatol. 2024;23(1):1355-1356.   doi:10.36849/JDD.7271.
