What is the first-line treatment for seasonal allergic rhinitis?

• A. Antihistamines
• B. Intranasal corticosteroids
• C. Antileukotrienes
• D. Oral corticosteroids

Answer: (B)

The first-line treatment for seasonal allergic rhinitis is intranasal corticosteroids. This class of medication is highly effective because they work by reducing inflammation in the nasal passages, thereby alleviating symptoms such as nasal congestion, sneezing, and runny nose. Intranasal corticosteroids have a strong evidence base supporting their efficacy and are recommended by allergy experts as the most effective long-term management option for allergic rhinitis.

While antihistamines are also commonly used to address symptoms of allergic rhinitis, they primarily counteract the histamine response which leads to allergy symptoms, but they do not address underlying inflammation as effectively as intranasal corticosteroids do. Antileukotrienes can be used for allergic rhinitis and may help to some extent, but they are usually not considered as the first-line option. Oral corticosteroids are effective for severe allergic reactions but are generally reserved for short-term use due to potential significant side effects when used long-term, thus not being the preferred treatment for typical cases of seasonal allergic rhinitis.
