Children with urticaria should be treated as early as possible with anti-allergy therapy. Cetirizine hydrochloride drops, loratadine syrup or diclofenac dry suspension are recommended for children with urticaria, and the specific dosage should be calculated in accordance with the instructions and body weight, or in accordance with the doctor’s instructions. The medication should be taken every day, regardless of whether or not the child has a rash that day, and should be continued for 2 weeks after the rash is under control before it is stopped. Carefully recall the allergens in your child’s life and try not to eat fish, shrimp, chili peppers and other irritating foods.
