Medication Summary
Medical therapy for diaper dermatitis includes the use of protective topical agents, topical anticandidal agents, and, possibly, topical low-potency steroids.
Protective topical agents
Class Summary
Ideally, first-line therapy for diaper dermatitis is zinc oxide ointment. The safest over-the-counter (OTC) emollient available for newborns is pure white petrolatum ointment. Another safe alternative is Aquaphor ointment, which is principally composed of white petrolatum, mineral oil, and lanolin. It is more expensive than pure white petrolatum ointment.
Petrolatum (Vaseline, Aquaphor, Aquabase)
Traps water beneath the epidermis.
Zinc oxide (Borofax Skin Protectant)
Has antiseptic and astringent properties. Plays significant role in wound healing with low risk for allergic or contact dermatitis. To remove zinc oxide from skin, mineral oil is more effective and easier than soap and water.
Petrolatum, zinc oxide, aluminum acetate solution (1-2-3 Paste)
Combination product that is both a skin protectant and has a drying effect on vesicular or wet dermatoses.
Antifungal agents
Class Summary
These agents are indicated for suspected candidiasis or proven candidal infection by potassium hydroxide (KOH) preparation or culture. Commonly used topical antifungal agents are nystatin cream or ointment and econazole nitrate cream.
Nystatin (Mycostatin)
Fungicidal and fungistatic antibiotic obtained from Streptomyces noursei. Effective against various yeasts and yeastlike fungi. Changes permeability of fungal cell membrane after binding to cell membrane sterols, causing cellular contents to leak.
Clotrimazole topical (Lotrimin AF)
Effective in cutaneous infections. Interferes with RNA and protein synthesis and metabolism. Disrupts fungal cell wall permeability, causing fungal cell death.
Econazole (Spectazole)
Effective in cutaneous infections. Interferes with RNA and protein synthesis and metabolism. Disrupts fungal cell wall permeability, causing fungal cell death.
Topical steroids
Class Summary
Limit potent topical steroid use to a few days and to a small quantity. Avoid combination topical steroid/antifungal cream in the diaper area.
Hydrocortisone, topical (Cortaid, Cortizone, Westcort)
An adrenocorticosteroid derivative suitable for application to skin or external mucous membranes. It has mineralocorticoid and glucocorticoid effects resulting in anti-inflammatory activity.
For diaper dermatitis, which has the appearance of irritant and candidal dermatitis, the author has good experience using hydrocortisone 1% cream or Desonide 0.05% cream (bid) with nystatin (qid).
