For patients with mycoplasma infections, erythromycin or azithromycin are feasible because both drugs belong to the macrolide class, which also includes roxithromycin, both of which are the drugs of choice for mycoplasma infections. If some patients are not sensitive to macrolides, they can be treated with fluoroquinolones, such as levofloxacin or moxifloxacin, etc. In addition, tetracyclines can also be used in the treatment of pneumonia and mycoplasma pneumonia, but tetracyclines have more adverse reactions and need to be used with caution, usually for 2-3 weeks to cure. Special attention should also be paid to the fact that Mycoplasma pneumoniae is a cell wall-less pathogen, so penicillin and cephalosporins are not effective against it, and care should be taken when using them to avoid their use.
