Can thrush harm my baby during pregnancy?

During pregnancy women often get thrush because of the changes going on in the body, especially during the third trimester. But there's no evidence that thrush can harm an unborn baby.

What is thrush?

Thrush is a yeast infection caused by the Candida species of fungus, usually Candida albicans. It usually lives harmlessly in the vagina and doesn't cause any symptoms, because its growth is kept under control by normal bacteria.

But if the balance of bacteria changes – for example, when you're pregnant, taking antibiotics, or under a lot of stress – the fungus can grow and cause:

  • white discharge (like cottage cheese), which doesn't usually smell
  • itching and irritation around the vagina and vulva 
  • soreness and stinging during sex or when you pee
  • redness

Treating thrush during pregnancy

If you're pregnant, you should see a GP or pharmacist before using treatments for thrush.

Thrush during pregnancy can be treated with cream or a tablet inserted in the vagina (a pessary) that contains clotrimazole or a similar antifungal drug.

Normally, thrush can also be treated with antifungal tablets called fluconazole. But, if you're pregnant, trying to get pregnant or breastfeeding, you shouldn't take anti-thrush tablets.

If you have thrush when your baby is born, the baby may catch it during the delivery. This is nothing to worry about and can easily be treated.
