Introduction
The primary symptoms of acute urticaria include large, widespread, or diffuse erythematous plaques, or wheals arising on an erythematous background, often accompanied by pruritus of varying severity. Due to its rapid onset and progression, some cases of acute urticaria may be associated with fever or general malaise of varying degrees; in more severe instances, patients may experience dyspnea or laryngeal edema.

Symptoms of Acute Urticaria
The primary manifestation of acute urticaria is widespread or diffuse erythematous plaques, or wheals developing on an erythematous background, often accompanied by pruritus of varying severity. Due to its rapid onset and progression, some cases of acute urticaria may be associated with fever or general malaise. In more severe instances, patients may experience dyspnea or laryngeal edema. Additionally, gastrointestinal symptoms—including nausea, vomiting, abdominal pain, and diarrhea—may also occur. Therefore, prompt pharmacological intervention is essential upon recognition of acute urticaria symptoms; uncontrolled progression may lead to life-threatening anaphylactic shock.
Causes of Urticaria:
• Allergic reactions—including food allergies (e.g., hypersensitivity to high-protein foods such as shellfish); drug allergies (e.g., penicillin-induced urticarial drug eruptions, one of the most common manifestations); and contact allergens (e.g., fertilizers or industrial chemicals).
• Infections—such as tonsillitis, chronic occult infections, fungal infections, or viral infections.
• Autoimmune disorders—including systemic lupus erythematosus.
• Physical triggers—such as pressure-induced urticaria or solar urticaria.
• In a substantial proportion of cases, the underlying cause remains idiopathic.
