P04: Fetus and newborn affected by noxious influences transmitted via placenta or breast milk

P04.4: Fetus and newborn affected by maternal use of drugs of addiction

The placenta forms in the mother’s womb during pregnancy. The placenta consists of cells from the mother and cells from the unborn child. The umbilical cord connects the child to the placenta. The child is supplied with nutrients and oxygen from the mother's blood via the placenta.

Medications or drugs can be transmitted from the mother to the child via the placenta. Medications or drugs can also affect the child via the mother's milk. The child's health can be harmed as a result.

Taking certain medications or drugs during pregnancy can cause deformities in the child. The child's development in the womb may also be different. After the birth, problems can occur with the child's breathing or circulation. Seizures or tremors may occur. There may be problems with nutrition and digestion. After the birth the child may then not develop as other children of the same age do.
