Is there a specific drug for treating artificial urticaria?
Disease description:
I am 25 years old this year. Recently, I noticed acne-like eruptions on my face accompanied by unusual itching, which has not improved. When I visited the hospital for evaluation, I was diagnosed with dermatographism (also known as “skin writing” or “artificial urticaria”). Is there a specific or highly effective medication for dermatographism?

There is no specific drug for artificial urticaria, also known as dermatographism. This condition is characterized by a classic triad: linear red wheals appear on the skin following scratching with a fingernail or stroking with a blunt object, followed by surrounding erythema. Treatment options commonly include transfer factor, procaine intravenous blockade, and antibiotics. In some cases, antihistamines—such as cyproheptadine or chlorpheniramine (H1-receptor antagonists)—may be used, often in combination with H2-receptor antagonists to enhance therapeutic efficacy. During treatment, patients are advised to follow a light, bland diet and avoid spicy or irritating foods.
