Which of the following is an example of an intranasal steroid?

Fluticasone is classified as an intranasal corticosteroid, which makes it effective in treating conditions like allergic rhinitis. Intranasal steroids work by reducing inflammation in the nasal passages, thereby alleviating symptoms such as nasal congestion, sneezing, and runny nose. They target the underlying inflammatory response associated with allergic reactions.

In contrast, the other options provided are oral antihistamines. Benadryl (diphenhydramine) and Claritin (loratadine) are known for blocking histamine receptors to reduce allergy symptoms but do not address inflammation directly. Allegra (fexofenadine) functions similarly as an antihistamine, providing relief from allergy symptoms without having an anti-inflammatory effect. Because Fluticasone directly addresses the inflammatory component of allergic rhinitis, it is essential for managing symptoms effectively and is recognized as an intranasal steroid.
