Detailed medicine guidance

Pregnancy, breastfeeding and fertility while using ketoconazole

NHS medicines information on ketoconazole and whether you can use it while pregnant or breastfeeding.

About this information

This NHS content is written for people in England. Medicine names, availability, prescribing and services may differ in other countries.

Ketoconazole and pregnancy

You can use ketoconazole cream or shampoo if you're pregnant.

Only tiny amounts are absorbed into your body so it will not affect your baby.

Ketoconazole and breastfeeding

It's OK to use ketoconazole cream or shampoo if you're breastfeeding. It's very unlikely that any will get into your breast milk.

If you're using ketoconazole cream for thrush (candida) of the breast, your baby will also need to be treated at the same time with their own medicine.

Take care that your baby does not touch any areas of your body where you've used ketoconazole. Wash your hands after you've used it and before picking up your baby. When using it on your breasts or nipples, wash it off before feeding your baby. It's important that your baby does not swallow any ketoconazole cream.

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.
