The treatment of anaphylactoid purpura is mainly to remove the allergic factors. We must actively search for and remove the incentives. At the same time, we should also apply some anti allergic drugs and anti infection drugs to alleviate symptoms. If the condition is serious or serious complications occur, glucocorticoid treatment is also required, and surgery may be required if necessary. During the treatment, you need to stay in bed and rest. You should actively find and avoid contact with allergens. If there is obvious infection, you should add effective antibiotics. If necessary, you can also use intravenous infusion to maintain the balance of water and electrolyte, and avoid taking some suspicious food or drugs. In addition, drugs to improve vascular permeability can be used in drug treatment, such as vitamin c, rutin and calcium. Antiallergic drugs such as antihistamine cetirizine, loratadine or calcium should also be used. You can also use some anti rheumatic drugs to improve the condition, such as hydroxychloroquine, dapsone or colchicine, which have good effects on skin rashes. Severe patients can also be treated by intravenous infusion of gamma globulin, and severe patients need to be treated with glucocorticoid. The above scheme is only for reference. Please use the drug according to the drug use instructions or the doctor's advice in a regular hospital.
