If your baby has a cough with wheezing symptoms, the preferred method of treatment is nebulized inhalation. Nebulized inhalation of budesonide, combined with cortisol, salbutamol, terbutaline, etc. is usually required. The specific situation needs to be judged based on the doctor’s hearing and understanding of the medical history, such as the frequency and dosage. However, if the cough and wheezing are more persistent, the possible causes need to be analyzed. If there is an infection present, the source of the infection needs to be determined, for example, blood tests, mycoplasma and other related tests need to be done and anti-infective drugs need to be selected as appropriate. Some babies with cough and wheeze are not related to infection but may have allergic factors, usually with a history of allergic rhinitis or eczema, and need to actively search for suspected allergens and try to avoid them in order to get to the root of the problem.
