Patients with allergic purpura can take baths, but the water temperature should not be too hot. This is because excessive heat or vigorous exercise can potentially trigger a recurrence of allergic purpura. Additionally, patients should avoid getting cold to reduce the risk of infection, as infections can also provoke episodes of allergic purpura. During an episode of allergic purpura, it is necessary to take some anti-allergy medications and medications that reduce rashes, such as desloratadine dispersible tablets and compound glycyrrhizin tablets. If there is significant involvement of vital organs, such as the kidneys or gastrointestinal tract, some patients may also need to use corticosteroids. (Medication should be taken under the guidance of a doctor.)
