Infant Thrush


Infant thrush

is a yeast infection of your infant's mouth. The same yeast may also cause a diaper rash. This yeast is a type of fungus called Candida. This yeast is normally present in your infant's mouth and digestive tract. Sometimes the yeast can overgrow and cause a yeast infection. Medicines such as antibiotics or steroids may increase your infant's risk of thrush.

Common symptoms include the following:

  • White patches on your infant's lips, tongue, or the inside of his cheeks that do not wipe off easily
  • Cracked skin on the corners of your infant's mouth
  • Mouth pain or soreness, which may cause decreased milk intake
  • A severe diaper rash at the same time

Seek care immediately if:

Your infant has signs of dehydration including any of the following:

  • Crying without tears
  • Urinating less than usual or not at all
  • Dry mouth

Contact your infant's healthcare provider if:

  • Your infant is drinking or eating less than usual.
  • Your infant has a fever.
  • There is bleeding in the areas where your infant has thrush.
  • You have questions or concerns about your condition or care.

Treatment for infant thrush

may include antifungal liquid medicine. This medicine will need to be applied to the areas of your infant's mouth that have thrush. You may also need to apply an antifungal cream to your infant's diaper area if he has a diaper rash.

Manage infant thrush:

  • Limit your infant's pacifier use if you think he has mouth pain. Sucking for long periods of time can irritate your infant's mouth. Try to use the pacifier only when you cannot find another way to calm your infant.
  • Feed your infant with a cup, spoon, or syringe instead of a bottle if you think he has severe mouth pain. He may not want to take the bottle if he has pain.
  • Wash the nipples from your infant's bottles and pacifiers in hot water or dishwasher after each use.
  • Apply antifungal cream to your nipples if you breastfeed and your nipples are red and sore. You may have also have a yeast infection on your nipples. Apply the cream to your nipples 4 times each day after you breastfeed your infant, or as directed.

Follow up with your child's doctor as directed:

Write down your questions so you remember to ask them during your child's visits.
