Seretide Evohaler is a prescription-only inhaler containing a combination of fluticasone propionate (50mcg) and salmeterol xinafoate (25mcg). This pressurized metered dose inhaler provides 120 doses and is CFC-free. It requires shaking well before each use. This medication is manufactured by GSK (GlaxoSmithKline) and must be kept out of reach of children. Each metered dose delivers precisely 50 micrograms of fluticasone propionate and 25 micrograms of salmeterol (as xinafoate) through the pressurized inhalation system. The purple and white packaging clearly indicates it is a prescription-only medicine that requires proper storage and handling.
