Pregnancy, breastfeeding and fertility while taking peppermint oil

Although there is not much information on the use of peppermint oil in pregnancy, it is not expected to cause any problems.

If your baby is healthy you can take peppermint oil if you need to while breastfeeding.

There's not much information about taking peppermint oil while breastfeeding but it's likely that only tiny amounts would get into breast milk. It's unlikely to cause any side effects in your baby.

It's very rare for breastfed babies to have side effects from medicines you're taking. But it's important to keep monitoring your baby if you're taking any medicine while breastfeeding.

Contact your healthcare professional or call 111 as soon as possible if you notice that your baby is not feeding as well as usual, has any unusual symptoms, or if you're worried about them.

Keep breastfeeding as usual until you've got advice about your baby's symptoms.
