If the elderly have lung infection with sputum and sticky sputum, they can be given oral cough suppressant and phlegm-relieving medications such as Ambroxol, acetylcysteine, eucalyptus citrus soft capsule and other phlegm-relieving and phlegm-promoting medications, or they can be given Chinese herbal medicines such as compound fresh bamboo lei and orange red pill. If an elderly person has a cough with weak phlegm, strong cough suppressants containing codeine should not be used to suppress the cough, otherwise it will affect the phlegm discharge and aggravate the condition. If the cough is persistent, the sputum is sticky and cannot be coughed up or yellow pus sputum is coughed up, you can go to the hospital and get blood tests, CRP, routine blood tests, calcitoninogen, chest X-ray and CT lung examination according to the doctor’s recommendations. If evidence of bacterial infection of pneumonia is found, aggressive treatment with antibiotics needs to be given. If the results are not good, nebulized inhalation can also be given to dilute the sputum and promote sputum discharge to reduce the symptoms.
