From the Guidelines
For a 9-year-old child with urticaria, I strongly recommend starting with over-the-counter (OTC) second-generation antihistamines like cetirizine (Zyrtec) 5-10mg once daily or loratadine (Claritin) 10mg once daily, as they are less sedating and provide 24-hour relief, according to the guidelines for evaluation and management of urticaria in adults and children 1.
Key Considerations
- The choice of antihistamine should be based on the individual's response and tolerance, with the option to try at least two different nonsedating H1 antihistamines 1.
- It is essential to follow the age-appropriate instructions on the package for dosing, typically 5mg for children under 6 years and 10mg for those over 6 years.
- If OTC treatments do not provide adequate relief after 1-2 weeks, consultation with a pediatrician is necessary to consider prescription-strength antihistamines like levocetirizine or desloratadine, or in severe cases, a short course of oral corticosteroids, as recommended for severe acute urticaria or angio-oedema affecting the mouth 1.
Additional Measures
- Identifying and avoiding potential triggers such as certain foods, medications, insect bites, or environmental factors is crucial in managing urticaria.
- Keeping the child's skin cool, as heat can worsen hives, and dressing them in loose-fitting clothing can help alleviate symptoms.
- Antihistamines work by blocking histamine receptors, preventing the chemical mediator responsible for the itchy, red welts characteristic of hives.
Important Notes
- Most childhood urticaria cases are acute and resolve within a few weeks, but if hives persist beyond 6 weeks or are accompanied by breathing difficulties, facial swelling, or other concerning symptoms, immediate medical attention is necessary.
- The use of sedating antihistamines as monotherapy is less common due to concerns about reduced concentration and performance, but they can be effective and well-tolerated by some individuals, and may be considered for addition at night to help with sleep 1.

From the Research
Urticaria Treatment for 9-Year-Old: Rx vs OTC
- The treatment of urticaria typically involves the use of antihistamines, with second-generation antihistamines being the preferred choice due to their safety and efficacy profile 2, 3, 4, 5.
- For a 9-year-old patient, the choice between prescription (Rx) and over-the-counter (OTC) medications depends on the severity and type of urticaria, as well as the patient's medical history and other factors.
- Second-generation antihistamines such as loratadine, cetirizine, and fexofenadine are available OTC and are considered safe and effective for the treatment of urticaria in children 2, 4, 6.
- However, in some cases, prescription-strength antihistamines or other medications such as leukotriene receptor antagonists or corticosteroids may be necessary to control symptoms 3, 5.
- It is essential to consult a healthcare professional to determine the best course of treatment for a 9-year-old patient with urticaria, as they can assess the patient's individual needs and provide guidance on the use of Rx or OTC medications.
Treatment Options
- Second-generation antihistamines:
- Loratadine
- Cetirizine
- Fexofenadine
- First-generation antihistamines:
- Chlorpheniramine

Special Considerations
- Children and adolescents may require lower doses of antihistamines, and the use of sedating antihistamines should be avoided whenever possible 6.
- Patients with a history of allergies or asthma may require closer monitoring and adjustment of their treatment plan 4, 5.
- In cases of severe or refractory urticaria, referral to a specialist may be necessary to explore alternative treatment options such as omalizumab or cyclosporine 3, 5.
