There is no clinical term for variant cough; it is considered to refer to cough variant asthma. Whether long-term medication is needed needs to be determined according to the cause of the disease and the extent of the disease. Cough variant asthma is associated with genetic and physicochemical factors, while climate change, respiratory infections, and exposure to irritating odors are triggering factors. For those with cough variant asthma, the acute phase can be treated with aerosols such as salmeterol and budesonide as prescribed by the doctor. The initial treatment usually takes 2 to 3 months, and the need for long-term treatment needs to be determined according to the cause of the disease and the extent of the disease. It is recommended that people with cough variant asthma use medication under the guidance of a physician, and should not use drugs or prescriptions on their own. Daily should create a good living environment, away from dust, pollen, paint and so on.
