Inhaled Cochlearone, known generically as fluticasone propionate inhalation aerosol, can only be inhaled through the mouth and can be assisted by a storage canister if patients have difficulty with synchronized inhalation and aspiration. Fluticasone propionate inhalation aerosol is mainly used for the prophylactic treatment of asthma in adults and children over 1 year of age. The main side effects of the drug are that some patients may develop candidiasis of the mouth and throat, which is helped by gargling with water after use of the drug, and locally with antifungal drugs. Patients who are allergic to the drug are prohibited from using it. The correct method of inhalation of the drug is as follows: first, shake the aerosol well up and down so that the liquid is well mixed. Then, gently and thoroughly spit out the air in the lungs, then put the mouthpiece into the mouth and hold it tightly, inhale deeply and slowly and quickly press the canister to release the drug, and continue to inhale, hold your breath for 5-10 seconds after inhalation, and then exhale slowly. Rinse the mouth well after use. If you need to use fluticasone propionate inhalation aerosol, it is recommended that you use it under the guidance of a doctor and master the correct method of inhalation to avoid delaying your condition.
