Henochromic purpura is generally curable, but some patients with serious conditions such as purpura nephritis are not curable. It is recommended that patients with purpura should seek medical treatment in time and take medication or other treatments. 1. If the condition of patients with purpura is mild, it is easy to treat, but patients with serious conditions may have complications such as purpura nephritis, and some patients with purpura nephritis may also have nephritis, nephrotic syndrome and uremia, which are not curable. It is recommended that patients who have been diagnosed with purpura should consult a doctor in time and take regular treatment. 2. Patients with purpura can use glucocorticosteroids such as dexamethasone injection and methylprednisolone sodium succinate injection as prescribed by the doctor, and can also take anti-allergy drugs such as loratadine tablets and chlorpheniramine maleate tablets orally.
