What Is Known And Objective:
Tegoprazan induces adverse drug reactions during clinical trials; however, tegoprazan-induced urticaria has not been reported. Here, we describe the first case of this.
Case Description:
A 55-year-old woman presented with acute urticaria with pruritus after taking the gastro-oesophageal reflux disease medication, tegoprazan. Urticaria disappeared after tegoprazan discontinuation. In an oral provocation test, after taking 10% of tegoprazan, she developed pruritus, and after taking 30%, she developed urticaria on her back.
What Is New And Conclusion:
This is the first case of urticaria induced by tegoprazan. Physicians should understand the possibility of a tegoprazan-induced hypersensitivity reactions.

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
