Infants with prickly heat should be relieved by general treatment and medication such as cetirizine hydrochloride drops. 1. General treatment: Although babies are relatively small, it is not advisable to give them thick clothes. Cotton breathable clothes should be the main focus, try to wear loose in summer, and try to let the infant stay in a cool, ventilated and breathable environment. Parents need to regularly wash the baby’s skin, then let the skin dry naturally, and if necessary, cold compresses can be applied to the skin. 2. Medication: You need to use baby-specific prickly heat powder, which can keep the skin lesions dry and promote the repair of the lesions. You can also use glycerine lotion or hydrocortisone ointment topically to relieve the symptoms. Parents are advised to bring their children to the doctor in time. As the skin of infants is relatively delicate, parents should not use medication on their own to avoid abnormal reactions.
