Children’s skin allergy with fever can be relieved by physical cooling and medication. If a child’s fever is caused by skin allergy, if the fever is mild and the mental condition is good, it can be treated by physical cooling first, such as using warm water or alcohol to wipe the body or reduce clothing. If the fever is severe and persists, acetaminophen and ibuprofen can be given as prescribed by the doctor to reduce fever. At the same time, pay attention to hydration and rationalize the diet. Antihistamine drugs such as loratadine can also be used for anti-allergy treatment. Generally, after the allergy symptoms are relieved, the symptom of elevated body temperature due to allergy will also be relieved. If the child’s fever does not go down, he should seek medical treatment, avoid contact with allergens, take rest and have a reasonable diet.
