Key takeaways
Flovent (fluticasone) and Asmanex (mometasone) are both inhaled corticosteroids used to manage asthma in people 4 years and older. Flovent is available in two forms: Flovent HFA and Flovent Diskus, while Asmanex comes as Asmanex HFA and Asmanex Twisthaler. One key difference is that Flovent is typically used twice a day, whereas Asmanex Twisthaler is often used once a day. Flovent HFA has a generic version available, which can be more cost-effective. Both medications require you to rinse your mouth after use to prevent fungal infections. Asmanex Twisthaler and Flovent Diskus cannot be used if you are allergic to milk proteins. Additionally, Flovent and Asmanex both have similar side effects, such as throat irritation and headache, and may take one to two weeks to show improvement in symptoms. Neither medication should be used as a rescue inhaler for sudden asthma attacks.
