What is a first-line therapy for managing seasonal allergies?

Intranasal corticosteroids are considered a first-line therapy for managing seasonal allergies due to their effectiveness in reducing inflammation in the nasal passages. These medications work by decreasing mucosal swelling, blocking the release of inflammatory substances, and alleviating symptoms such as nasal congestion, sneezing, and itching. They are preferred because they address the underlying cause of allergic rhinitis rather than just masking the symptoms, providing a more comprehensive treatment approach.

Moreover, intranasal corticosteroids have a favorable safety profile and can be used for both seasonal and perennial allergy symptoms. They are typically well-tolerated and can be used long-term, making them a practical choice for individuals who suffer from allergies frequently. Other options, such as leukotriene modifiers and oral corticosteroids, may also be effective but are generally not the first recommendation due to their varying mechanisms of action and potential side effects.
