Multicenter StudyIncreased incidence of neonatal vitamin K deficiency resulting from maternal anticonvulsant therapy.
The null hypothesis of our study is that the incidence of vitamin K deficiency in mother-infant pairs exposed to anticonvulsant drugs is not higher than in controls. ⋯ The incidence of vitamin K deficiency is increased in neonates exposed to anticonvulsant drugs prenatally. Their mothers, however, are rarely vitamin K deficient.
