There is no such thing as what is the correct treatment for allergic purpura. This disease can be treated with general measures, medication, and other treatments, and the doctor will formulate an appropriate treatment plan according to the condition. 1. General measures: patients need to remove various pathogenic factors, avoid contact with allergens, pay attention to the cleanliness of the affected skin, avoid scratching. If it is in the acute stage, bed rest is required, avoiding strenuous exercise, can take a comfortable position, elevate the purpura and edema parts. 2. Drug treatment: patients need to follow the doctor’s instructions to use antihistamines, such as cetirizine, chlorpheniramine and so on. For mild and moderate pain, non-steroidal anti-inflammatory drugs (NSAIDs), such as acetaminophen and ibuprofen, can be used as prescribed by the doctor. For severe pain, glucocorticosteroids such as methylprednisolone and dexamethasone are prescribed. If the effect of glucocorticoid drug treatment is not good, then we should follow the doctor’s advice to use cyclophosphamide, azathioprine and other immunosuppressive drugs. 3. Other treatments: For patients with refractory allergic purpura who are not well treated with the conventional treatments mentioned above and who suffer from recurrent episodes, plasma replacement therapy should be carried out in cooperation with the doctor. To summarize, patients with purpura need to go to the hospital in time, cooperate with doctors to actively treat, and strengthen daily life management.
