What is a typical first-line treatment for a child experiencing mild allergic rhinitis?

A typical first-line treatment for a child experiencing mild allergic rhinitis is antihistamines. Antihistamines work by blocking the action of histamine, a substance released during an allergic reaction that causes symptoms such as sneezing, itching, and runny nose. They are effective in alleviating these symptoms, making them a suitable choice for mild cases of allergic rhinitis.

Intranasal corticosteroids are often used for more moderate to severe symptoms and provide effective long-term control of inflammation but are typically not the first step when a child's symptoms are mild. Oral antibiotics are not appropriate because allergic rhinitis is not an infection; thus, they do not address the underlying cause. Decongestants can provide temporary relief from nasal congestion but do not treat the root cause of allergic symptoms and may have side effects that limit their use in children. Therefore, antihistamines are the most appropriate choice for managing mild allergic rhinitis in pediatric patients.
