Anti-inflammatory drugs are generally the popular name for antibiotics. Ground glass lung nodules should be treated differently depending on the cause, and antibiotics should not be taken blindly. Ground glass lung nodules may be benign lung diseases (e.g. pneumonia), precancerous lesions (e.g. atypical adenomatous hyperplasia), or lung cancer (e.g. adenocarcinoma in situ), and should be treated according to the patient’s condition and clinical examination. Overall management principle: If the ground-glass lung nodule is relatively small and the patient has no other uncomfortable symptoms, it can be observed clinically and does not need drug treatment. Chest CT can be repeated in 3-6 months. 1. Benign diseases: For lung ground-glass nodules caused by benign diseases, they do not need special treatment, and can be followed up or treated for the primary disease. In most cases, antibiotics are not needed. If it is caused by inflammation and there are indications for treatment, azithromycin, levofloxacin and other antibiotics can be considered as appropriate for treatment. 2. For tumor lesions, close follow-up or surgical resection is needed as soon as possible to avoid tumor progression which may lead to serious consequences. It is recommended to pay more attention to rest, avoid overwork and mental stress, pay attention to keep warm, avoid getting cold, etc., and pay attention to the combination of work and rest. You can go to the hospital to check the blood routine and review the CT examination of the lungs regularly to observe the development of the lesion. All the above medications should be used under the guidance of a doctor, avoid self-medication.
