Urethral orifice is a bit red and swollen can you use erythromycin ointment?

Erythromycin ointment is a kind of macrolide antibacterial anti-inflammatory drug, which has good therapeutic effect on infection caused by sensitive bacteria, but if it is caused by fungal infection, erythromycin ointment is almost no clinical effect. In addition to infection, other factors include allergies, foreign body irritation, trauma, etc. These factors are also ineffective with erythromycin, requiring the application of anti-allergic drugs or removal of foreign body irritation to carry out targeted treatment.
