Mild OE usually responds to the use of an acidifying agent and a corticosteroid. As an alternative, a 2:1 ratio mixture of 70% isopropyl alcohol and acetic acid may be used. For moderate OE, consideration should be given to adding antibacterial and antifungal agents to the acidifying agent and the corticosteroid.
