    Diaper rash

    Dermatitis - diaper and Candida; Candida-associated diaper dermatitis; Diaper dermatitis

    A diaper rash is a skin problem that develops in the area beneath an infant's diaper.


    Diaper rashes are common in babies between 4 and 15 months old. They may be noticed more when babies begin to eat solid foods.

    Diaper rashes caused by infection with a yeast (fungus) called Candida are very common in children. Candidagrows best in warm, moist places, such as under a diaper.Candida diaper rash is more likely to occur in babies who:

    • Are not kept clean and dry
    • Are taking antibiotics or whose mothers are taking antibiotics while breast feeding
    • Have more frequent stools

    Other causes of diaper rash include:

    • Acids in the stool (seen more often when the child has diarrhea)
    • Ammonia (a chemical produced when bacteria break down urine)
    • Diapers that are too tight or rub the skin
    • Reactions to soaps and other products used to clean cloth diapers


    You may notice the following in your child's diaper area:

    • Bright red rash that gets bigger
    • Veryred and scaly areas on the scrotum and penis in boys
    • Red or scaly areas on the labia and vagina in girls
    • Pimples, blisters, ulcers, large bumps, or sores filled with pus
    • Smaller red patches (called satellite lesions) that grow and blend in with the other patches

    Older infants may scratch when the diaper is removed.

    Diaper rashes usually donot spread beyond the edge of the diaper.

    Exams and Tests

    Your doctor or nurse can often diagnose a yeast diaper rash by looking at your baby's skin. A KOH test can confirm if it is Candida.


    The best treatment for a diaper rash is to keep the diaper area clean and dry. This also helps prevent new diaper rashes. Lay your baby on a towel without a diaperwhenever possible. The more time the baby can be kept out of a diaper, the better.

    Other tips include:

    • Change your baby's diaper often and as soon as possible after the baby urinates or passes stool
    • Use water and a soft cloth or cotton ball to gently clean the diaper area with every diaper change.Do notrub or scrub the area. A squirt bottle of water may be used for sensitive areas.
    • Pat the area dry or allow to air-dry.
    • Put diapers on loosely. Diapers that are too tight do notallow enough air flowand may rub and irritate the baby's waist or thighs.
    • Using absorbent diapers helps keep the skin dry and reduces the chance of getting an infection.
    • Always wash your hands before and after changing a diaper.
    • Ask your doctor or nurse which creams, ointments, or powders are best to use in the diaper area.
    • Ask if a diaper rash cream would be helpful. Zinc oxide or petroleum jelly-based products help keep moisture away from baby's skin when applied to completely clean, dry skin.
    • Donot use wipes that have alcohol or perfume. They may dry out or irritate the skin more.
    • Do notuse corn starch on your baby's bottom. It can make acandida diaper rash worse.
    • Donot use talc (talcum powder). It can get into your baby's lungs.

    Certain skin creams and ointments will clear up infections caused by yeast. Nystatin, miconazole, clotrimazole, and ketaconazole are commonly used medicines for yeast diaper rashes. You can buy these without a prescription.

    Sometimes a mild corticosteroid cream may be used. Talk to your doctor before trying this on your baby.

    If you use cloth diapers:

    • Do not putplastic or rubber pants over the diaper. They do not allow enough air to pass through.
    • Do not use fabric softeners or dryer sheets. They may make the rash worse.
    • When washing cloth diapers, rinse 2 or 3 times to remove all soap if your child already has a rash or has had one before.

    Outlook (Prognosis)

    The rash usually responds well to treatment.

    When to Contact a Medical Professional

    Call your health care provider if:

    • The rash gets worse or does not go away in 2to 3 days
    • The rash spreads to the abdomen, back, arms, or face
    • You notice pimples, blisters, ulcers, large bumps, or sores filled with pus
    • Your baby also has a fever
    • Your baby develops a rash during the first 6 weeks after birth
