But its wrong to use it at will, which will lead to the problem of bacterial resistance to antibiotics. There is a long consensus on the use of external antibiotics in clinical practice: if there are corresponding oral preparations, try not to use or use less antibiotic ointment. Long term or frequent use of erythromycin ointment is likely to lead to bacterial resistance to erythromycin, and then cross resistance to macrolides like erythromycin, such as azithromycin, erythromycin succinate and roxithromycin, which are well known as the first-line drugs for the treatment of Mycoplasma or Chlamydia pneumoniae. In fact, if the local use of antibiotics is really needed, we can choose the antibiotic ointment without cross resistance risk, such as mupirocin ointment and fusidic acid cream.
Therefore, erythromycin ointment seems omnipotent, in fact, it can only be used as a temporary substitute in many cases. In addition to anti infection is its job, other uses are not very suitable.
