Children with urticaria should choose medications under the guidance of a doctor, usually focusing on anti-allergy drugs, and the medications should be adjusted according to the specific symptoms.

1. **Commonly Used Oral Medications:** Doctors often recommend using antihistamines suitable for children, such as cetirizine drops or loratadine syrup. These medications help relieve itching and reduce hives.

2. **Topical medication assistance:** If the skin itching is significant, topical medications such as calamine lotion can be applied under the guidance of a doctor to help temporarily relieve itching and soothe the skin.
3. **Special Case Management:** If accompanied by shortness of breath, swelling of the eyelids or lips, this may indicate a serious reaction and requires immediate medical attention. The doctor may prescribe other medications as needed.
In general, always consult a pediatrician or dermatologist before giving your child any medication; never buy medication on your own. Also, keep a record of the food or environment your child was exposed to before the flare-up, as this can help identify the cause. Wearing loose-fitting cotton clothing and avoiding overheating and scratching can also help relieve discomfort.
