Which treatment is considered first-line for managing allergic rhinitis?

Intranasal corticosteroids are recognized as the first-line treatment for managing allergic rhinitis due to their effectiveness in reducing inflammation and controlling symptoms such as sneezing, itching, runny nose, and nasal congestion. These medications work by directly targeting the inflammation in the nasal passages, leading to significant improvement in overall symptoms.

Evidence supports that intranasal corticosteroids not only provide relief from symptoms but also address the underlying inflammation, which is a key component of allergic rhinitis. They are more effective than oral antihistamines for nasal congestion and are safe for long-term use when prescribed appropriately.

Oral antihistamines are beneficial for relieving symptoms like sneezing and itching but do not effectively treat nasal congestion. Leukotriene receptor antagonists can provide symptom relief but are generally considered less effective compared to intranasal corticosteroids. Intranasal decongestants can relieve congestion temporarily but are not recommended for long-term use due to the risk of rebound congestion.

Overall, intranasal corticosteroids are the preferred choice, especially for moderate to severe cases of allergic rhinitis, due to their comprehensive approach to controlling both symptoms and the underlying allergic response.
