Pneumonia patients can choose moxifloxacin for infusion, because moxifloxacin has a broader antibacterial spectrum and is particularly effective against most common pathogens, especially when combined with moxifloxacin in severe infections and mycoplasma infections. However, if the patient’s infection is relatively mild, it is recommended to choose a low-grade antibiotic, or according to the results of sputum bacterial culture and drug sensitivity test to choose sensitive antibiotic treatment. However, moxifloxacin is not suitable for all patients, it is not recommended for pregnant women and minors under 18 years of age, because of bone inhibition, fetal teratogenicity and other occurrences, and the use of moxifloxacin should also pay attention to the presence of allergies.
