title: Does vitamin K prophylaxis prevent bleeding in neonates exposed to enzyme-inducing antiepileptic drugs in utero?
abstract: OBJECTIVE
  One of my epileptic patients takes carbamazepine. She is 36 weeks pregnant and has asked me whether she should start vitamin K to prevent neonatal bleeding. Does current evidence support this practice?
  
  
  CONCLUSIONS
  Recent evidence does not support the notion that newborns of women treated with enzyme-inducing anticonvulsant drugs are at increased risk of hemorrhagic disease. Antenatal vitamin K can be prescribed on an individualized basis in certain circumstances, such as imminent premature delivery.
