Patients with allergic purpura should not eat durian, as durian is considered a food that can trigger allergies, which in turn can provoke the onset of allergic purpura. Besides avoiding such trigger foods in their diet, patients with allergic purpura should also avoid getting cold, as catching cold can lead to infections, which may also trigger an episode of allergic purpura. Furthermore, intense physical activity, like fast running, should be avoided as well, because such activities can also lead to outbreaks of allergic diseases. Allergic purpura is also a self-limiting disease, and can improve on its own after reaching adulthood.
