What is the first-line treatment for allergic rhinitis?

Intranasal corticosteroids are considered the first-line treatment for allergic rhinitis due to their effectiveness in reducing inflammation within the nasal passages. They work by targeting the underlying inflammatory processes associated with allergic reactions, leading to significant improvements in symptoms such as nasal congestion, sneezing, and itching.

These medications demonstrate a rapid onset of action and have a favorable safety profile when used as directed. Their ability to control multiple symptoms of allergic rhinitis—like nasal obstruction and rhinorrhea—makes them a comprehensive treatment choice. Additionally, regular use of intranasal corticosteroids can help in minimizing future symptom exacerbations, providing both immediate relief and long-term management of allergic rhinitis.

Oral decongestants can temporarily relieve nasal congestion but do not address the underlying allergic inflammation, making them less suitable as a first-line option. While oral antihistamines are effective for treating symptoms associated with allergic rhinitis, they may not be as effective as intranasal corticosteroids in managing nasal congestion. Antibiotics are not appropriate for allergic rhinitis as it is an allergic condition rather than an infection.
