Abstract

Chronic urticaria (CU) is a hive-like rash lasting over six weeks. Common associations include low vitamin D, thyroid autoantibodies, and Helicobacter pylori (H. pylori) infection, among others. Progesterone has been documented to trigger CU, by endogenous or exogenous progesterone. The use of intrauterine devices (IUDs) has been a popular source of birth control, with many containing progesterone. Although rarely reported, some patients have been seen to have an urticarial reaction after implantation of an IUD. Here, we present a case of a patient with progesterone-induced chronic urticaria, likely triggered by implantation of a 13.5 mg intrauterine device implant (Skyla®, Bayer, Whippany, NJ, USA). To the best of our knowledge, this is the first case to report the association between Skyla® and chronic urticaria.

Keywords: allergy; autoimmune progesterone dermatitis; chronic urticaria; immunology; intrauterine device; iud; levonorgestrel; progesterone; rash; skyla.
