If the patient has a wound, the wound will not heal quickly after applying erythromycin ointment, but may affect the wound healing. In clinical practice, it is not recommended that patients should apply any ointment with antibacterial effect after a wound occurs, including erythromycin ointment. Only when the wound is infected, erythromycin ointment can be applied around the wound, and the ointment cannot be applied inside the wound. Erythromycin ointment has no effect on promoting wound healing. If the condition requires, you can apply some ointment to the wound, such as MEBO. You can also spray some liquid medicine with the effect of removing decay and regenerating muscles into the wound, such as Kangfuxin Liquid, to promote the wound healing. The above scheme is only for reference. Please use the specific drugs under the guidance of professional doctors according to your own conditions.
