*'''[[Methotrexate]]''' is typically used as a treatment for autoimmune disorders and cancer by inhibiting the metabolism of folic acid, the B vitamin necessary for cell division. Methotrexate attacks the fast-growing cells called trophoblasts, which essentially are life support for the fetus. The trophoblasts draw oxygen and nutrients from the mother's blood supply.<ref name="life" /> Deprived of nutrition and oxygen, the baby dies.
