Pregnancy, breastfeeding and fertility while taking or using nystatin - Brand name: Nystan

Nystatin and pregnancy

You can use nystatin while you're pregnant or trying for a baby.

Nystatin and breastfeeding

You can use nystatin while you're breastfeeding.

Nystatin has been used for many years without side effects in breastfed babies. It's not thought to pass into breast milk.

If you're using a cream or ointment containing nystatin, take care that your baby does not touch any areas of your body where you've used it. Wash your hands after you've used it and before picking up your baby.

If you're breastfeeding and you have thrush (candida) of the breast, you can use nystatin to treat this, although other treatments are usually more effective. Your baby will also need to be treated at the same time with their own medicine.

When using it on your breasts, wash it off your breasts or nipples, then wash your hands before feeding your baby. It's usually better to use cream rather than ointment when breastfeeding, as it's easier to wash off.

Creams and ointments containing nystatin may also contain other ingredients such as steroids, antibacterials and antiseptics. It's still OK to use them while breastfeeding.

If you notice that your baby is not feeding as well as usual, or if you have any other concerns about your baby, talk to your midwife, health visitor or doctor as soon as possible.

Nystatin and fertility

There's no evidence to suggest that nystatin will reduce fertility in either men or women.
