Introduction

Zinc oxide primarily exerts astringent and antipruritic effects, and also possesses mild drying properties. Zinc oxide ointment is indicated for acute and chronic dermatitis, eczema, miliaria (prickly heat), and minor, small-area skin ulcers. However, caution is advised: this medication should not be applied to broken or ulcerated wounds, as doing so may exacerbate bacterial infection, potentially leading to localized erythema and pain.

Zinc oxide is the oxide of zinc—a highly stable, white, water-insoluble powder. Zinc oxide ointment is commonly used to treat skin inflammation. So, what are the actions and benefits of zinc oxide? The following section addresses this question.

Can zinc oxide ointment be used for diaper rash in infants?

Zinc oxide ointment is commonly used to treat eczema and dermatitis and may be applied to the perianal area. It is also suitable for infantile miliaria (prickly heat). However, for perianal eczema, zinc oxide ointment alone is often suboptimal. Perianal eczema is frequently associated with fungal infection and accompanied by intense pruritus; thus, both the fungal infection and pruritus must be controlled simultaneously. In such cases, topical application of ketoconazole cream (e.g., “Pikangwang”), desonide ointment, or “Youduo’er” ointment yields better results.
