How to Treat Purpuric Dermatitis

Purpuric dermatitis is an allergic vasculitis, also known as allergic purpura. It is most commonly triggered by allergic reactions and manifests with symptoms such as pruritus (itching) and subcutaneous hemorrhage. Without prompt and appropriate treatment, purpuric dermatitis may progress to purpuric nephritis. So, how is purpuric dermatitis treated? Let’s explore the options below.

How to Treat Purpuric Dermatitis

1. Pharmacological Treatment

Treatment of purpuric dermatitis is relatively complex. Antihistamines—such as cetirizine and loratadine—may be prescribed. Additionally, vitamin C, vitamin E, and calcium gluconate tablets may be used. In severe cases, topical corticosteroid preparations may be applied. Traditional Chinese medicine (TCM) formulations aimed at tonifying qi, invigorating blood circulation, and resolving stasis may also be employed.

2. Lifestyle and Dietary Management

Patients with purpuric dermatitis must prioritize adequate rest and avoid excessive fatigue. When resting, elevate the affected limb to promote optimal blood circulation. Dietary restrictions are essential: avoid spicy and stimulating foods—including chili peppers and coffee—as well as common allergens such as seafood, eggs, dairy products, shrimp, and crab. Alcohol consumption and smoking are strictly prohibited.

3. Long-Wave Ultraviolet (UVA) Phototherapy

In conjunction with pharmacological therapy, long-wave ultraviolet (UVA) irradiation can serve as an effective adjunctive treatment for purpuric dermatitis. UVA phototherapy is a widely utilized physical therapy modality.

The above outlines the key approaches to treating purpuric dermatitis. During treatment, patients should ensure sufficient rest, strictly adhere to their physician’s instructions regarding medication, and never discontinue therapy without medical guidance—doing so may lead to disease recurrence.
