6 hours after vaginal delivery / 6-12 hours after C-section: Postpartum period

Anticoagulant of Choice

Preconception dose of warfarin < 5mg/day: Continue warfarin + Aspirin
Preconception dose of warfarin ≥ 5mg/day: LMWH + Aspirin

Management of Patient on Warfarin at Time of Delivery

Stop warfarin.
Deliver by Cesarean section.
Administer Vitamin K to the mother and baby.

Anti-epileptics

Lamotrigine and Levetiracetam are the least teratogenic anti-epileptics.

Therapeutic Decision Making
