Pneumonia can be cured without injections and medications, but it depends on the severity of the lung infection and the germs that the patient has contracted. Patients with pneumonia are best treated with a sputum culture plus a drug sensitivity test to select antibiotics if available. The most common causative agents of community-acquired pneumonia are Streptococcus pneumoniae and Haemophilus influenzae, and the most commonly used drugs are cephalosporins, macrolides, and respiratory quinolones. Patients with pneumonia, if the lung infection is not particularly serious, no hypertension, diabetes, coronary heart disease, autoimmune diseases and other underlying diseases, you can first take oral antibiotics for 3 days to see if the symptoms have improved, if not recommended to switch to infusion therapy, the general course of treatment takes 10-14 days.
