Cough and sputum in the elderly are considered to be combined with bacterial infections, as the elderly generally have underlying diseases or low immunity, and should be treated with antibiotics, such as cephalosporins or levofloxacin, which are effective for community-acquired pneumonia or bronchitis. You can also use traditional Chinese medicine to resolve phlegm, such as orange red phlegm cough liquid, lung power cough combination, Nian Ci Um Chuan Bei Loquat Paste, and compound fresh bamboo leech liquid, which need to be used with evidence. Cough and phlegm should also be treated with sputum thinners, such as aminoglutethimide and acetylcysteine, to help dilute the phlegm and promote its discharge. For elderly people with cough and sputum, it is still recommended to go to the hospital for further examination of chest CT or chest X-ray to clarify whether the disease is of the lung.
