Hives in Children: Causes, Symptoms, and Treatment

Hives in children are a common skin condition characterized by itchy, red, raised welts that can appear suddenly and usually disappear within 24–48 hours. Common triggers include food allergies, medications, infections, insect bites, dust mites, and pollen. Most cases are mild and resolve on their own, but recurrent symptoms lasting longer than six weeks may indicate chronic urticaria. Treatment focuses on avoiding triggers and using antihistamines to relieve itching. Seek immediate medical attention if your child experiences facial swelling, severe abdominal pain, or difficulty breathing. Proper skin care and allergen avoidance can help reduce the risk of future flare-ups.

They typically appear as:

Itchy, raised, red, swollen welts with well-defined borders.

The rash usually develops suddenly and resolves within 24–48 hours, although it may recur.

If hives come and go for more than 6 weeks, the condition is called chronic urticaria (chronic hives).
