What is the first-line treatment for allergic rhinitis?

Intranasal corticosteroids are considered the first-line treatment for allergic rhinitis due to their efficacy in reducing inflammation and controlling symptoms associated with allergic reactions. These medications work directly at the site of action in the nasal passages, providing quick relief from nasal congestion, runny nose, itching, and sneezing caused by allergens.

The advantage of intranasal corticosteroids is their ability to address the underlying inflammatory process of allergic rhinitis, unlike other treatment options that may only target specific symptoms. They are effective for both seasonal and perennial allergic rhinitis and can be used long-term if necessary.

In contrast, while oral antihistamines effectively control allergic symptoms such as sneezing and itching, they do not reduce nasal congestion as effectively as intranasal corticosteroids. Decongestants may provide temporary relief from nasal congestion but do not have a long-term role in managing the underlying inflammation of allergic rhinitis. Additionally, antibiotics are not suitable for treating allergic rhinitis, as it is not caused by a bacterial infection.
