Pregnancy and breastfeeding
Many drugs can cross the placenta and affect an unborn child.
In general, using drugs when pregnant can increase the chances of going into labour early. This can mean that babies are born below the normal birth weight.
If a mother uses drugs while breastfeeding, they may be present in her milk, and could affect the baby.
Check with your health professional if you are taking or planning to take any drugs during pregnancy, or while breastfeeding.
