Lactulose and pregnancy
Lactulose can be taken during pregnancy and is not harmful to your baby.
Lactulose and breastfeeding
If your doctor or midwife says your baby is healthy, it's OK to take lactulose while you are breastfeeding.
Lactulose does not pass into breast milk so it's very unlikely to cause any side effects in your baby. However, it is always better to treat constipation without taking a medicine first.
If your baby is not feeding as well as usual, or has diarrhoea, or if you have any other concerns about your baby, then talk to your health visitor, midwife, pharmacist or doctor.
Lactulose and fertility
There's no evidence to suggest that taking lactulose should cause any fertility problems in either men or women.
