If your two-and-a-half-year-old baby has a bad cough at night, you can give nebulized inhalation to temporarily relieve the cough. The nebulized inhalation medications include budesonide suspension for inhalation and terbutaline sulfate nebulized solution. The main thing is to clarify the cause of the cough, most of which is caused by infectious factors such as bacterial, viral, mycoplasma and other pathogenic infections that can cause bronchitis and bronchopneumonia. Other causes of cough include allergic cough, cough variant asthma, and foreign body inhalation. If your child has a severe cough, it is recommended to do blood tests, C-reactive protein, mycoplasma antibodies, allergens, lung CT, chest X-ray and other related tests to clarify the cause of the cough and then treat the cause.
