In the clinical use of Azithromycin for the treatment of Mycoplasma pneumoniae infection, generally on average for about 1-2 courses of treatment, especially for relatively mild initial infection of Mycoplasma pneumoniae caused by bronchitis, pneumonia, etc., the use of Azithromycin 1 course of treatment is also about 2 weeks to be able to achieve complete cure. For some patients with poor immunity, it is easy to have recurrence of Mycoplasma pneumoniae in the body due to unclear clearance, so generally 2 courses of treatment can be used, for example, about 1 month. However, the side effects of azithromycin are mainly gastrointestinal irritation, manifested as nausea, vomiting, diarrhea, so the course of use is adjusted according to the patient’s reaction, and if the side effects are more obvious, you can also choose quinolones, such as levofloxacin.
