Key takeaways
Flunisolide (Nasalide) and Asmanex (mometasone) are both corticosteroids, but they are used for different conditions and administered differently. Flunisolide is a nasal spray used to treat nasal symptoms caused by seasonal or year-round allergies in people 6 years and older. It helps reduce inflammation in the nose to relieve symptoms like congestion and sneezing. On the other hand, Asmanex is an inhaler used for the maintenance treatment of asthma in people 4 years and older. It works by reducing lung inflammation to keep airways open and prevent asthma attacks. Flunisolide is typically used twice daily, while Asmanex can be used once or twice daily depending on the type of inhaler and the prescribed dose. Flunisolide is available as a lower-cost generic, whereas Asmanex is available in two forms: HFA inhaler and Twisthaler. Additionally, Asmanex Twisthaler contains lactose, which can be an issue for those allergic to milk proteins. Both medications have side effects related to their corticosteroid nature, such as potential growth delays in children and altered stress hormone levels, but they target different parts of the respiratory system.
