Dicloretadine is a common desensitizing medication for children, which is often used in children with allergies caused by improper eating, or allergic reactions to dust, air, etc., hives, or cough, sputum, wheezing, or respiratory illnesses, and can be given orally to treat this series of allergic manifestations. For better treatment, oral dicloxacin can be combined with oral vitamin C or oral calcium gluconate to provide rapid relief of allergic symptoms. If the oral treatment of pediatric allergy symptoms do not have a significant effect, it is necessary to go to the hospital for intramuscular injection or intravenous infusion of desensitizing drugs for treatment.
