Allergic purpura cannot be cured, and can only be clinically cured through general measures, medication, and other treatments. 1. General measures: patients need to actively search for causative factors and avoid contact with allergens. In the acute stage, bed rest is needed, avoiding too much walking activities. Those with mild abdominal pain can eat a small amount of easily digestible food, while those with severe abdominal pain need to fast and be given extra-gastrointestinal nutritional support therapy. At the same time, the patient can elevate the purpura and edema parts, keep the local skin clean. 2. Pharmacotherapy: For patients with pain, non-steroidal anti-inflammatory drugs (NSAIDs) such as naproxen and ibuprofen can be used as prescribed by the doctor. If the therapeutic effect is not good, the use of prednisone, cyclophosphamide, tacrolimus and other immunosuppressive drugs as prescribed by the doctor. Some patients also need to use antihistamines such as loratadine and cetirizine. 3. Other treatments: For patients with recurring and refractory conditions, plasma replacement therapy should be adopted in cooperation with the doctor. All in all, the allergic purpura has a certain recurrence, so it can’t be cured. Patients need to go to the hospital in time, cooperate with the doctor to carry out standardized treatment, strengthen the daily life management, and regular follow-up.
