Core Viewpoint - Erythromycin ointment is widely used for various conditions, but its application is often inappropriate and constitutes misuse [1][3]. Misuse Scenarios - Erythromycin ointment is promoted as a "universal medicine" for conditions such as insect bites, eczema, acne, athlete's foot, and even for treating diaper rash in infants [3]. - For diaper rash, the primary treatment should focus on moisturizing, reducing irritation, and anti-inflammatory measures rather than solely relying on erythromycin ointment [4]. Treatment Recommendations - Effective treatment for diaper rash includes applying moisturizing creams, minimizing diaper wear time, and using appropriate topical medications based on the severity of inflammation [4]. - In cases of insect bites, while erythromycin ointment can reduce the risk of infection, it does not relieve itching or inflammation [5][6]. - Erythromycin ointment is not effective for eczema, where the treatment should focus on moisturizing and anti-inflammatory agents [7]. - For acne, erythromycin ointment is insufficient as acne treatment requires a multifaceted approach [8]. - Athlete's foot, a fungal infection, necessitates antifungal treatment, which erythromycin does not provide [9]. Appropriate Use Cases - The suitable application of erythromycin ointment is primarily for treating minor burns and wounds where there is a risk of infection [10][11]. - It can be used for minor abrasions and superficial burns after proper cleaning and disinfection, but should not be used continuously for more than one week [12].
