Introduction
Flonase and Nasacort are two common medications used for managing symptoms of allergic rhinitis, such as nasal congestion, sneezing, and a runny nose. These over-the-counter nasal sprays belong to a class of drugs known as corticosteroids and work by reducing inflammation in the nasal passages. Although they are similar in function, there are some differences worth understanding when choosing the right medication for your needs.
