Dexamethasone sodium phosphate can be used in children because it is a glucocorticoid and a long-acting glucocorticoid that can have effective anti-inflammatory and anti-allergic effects. If children have atopic dermatitis, they can apply dexamethasone for relief. Dexamethasone can also be used to relieve acute urticaria in children with an itchy skin rash. If a child has an acute attack of asthma, dexamethasone can be given to the child for treatment. However, because dexamethasone is more potent and has a longer maintenance time, it should be applied again with strict indications to avoid long-term application causing adverse reactions in children, such as the appearance of buffalo back and full moon face in children.
