Flovent Inhaler is a brand name for a medication that contains the active ingredient fluticasone propionate. It is primarily used in the treatment of asthma. Fluticasone propionate is a corticosteroid, and inhaled corticosteroids are a mainstay in the management of asthma symptoms and prevention of asthma exacerbations. Flovent Inhaler works by reducing inflammation in the airways, which is a key factor in asthma. By reducing inflammation, it helps to prevent or decrease the frequency and severity of asthma symptoms such as wheezing, shortness of breath, chest tightness, and coughing. It's important to note that Flovent is not a rescue inhaler for immediate relief of asthma symptoms during an acute attack. Instead, it's used as a maintenance medication to be taken regularly, even when you're feeling well, in order to keep asthma symptoms under control and to reduce the risk of asthma exacerbations.
