Early pregnancy cerebral venous thrombosis and status epilepticus treated with levetiracetam and lacosamide throughout pregnancy

We describe a pregnant woman with a massive CVT in early pregnancy, complicated by status epilepticus. The mother was treated with levetiracetam, lacosamide and enoxaparin throughout pregnancy. A male infant was born on pregnancy week 36, weighing 2.2 kilogram. Both levetiracetam and and lacosamide were present in cord blood in levels similar to those in maternal blood. The infant was partially breast-fed and experienced poor feeding and sleepiness, starting to resolve after two first weeks. Milk samples were drawn five days after the delivery and a blood sample from the infant three days later. Lacosamide level in milk was low, resulting in an estimated relative infant dose of 1.8% of the maternal weight-adjusted daily dose in a fully breast-fed infant. This is the first case describing lacosamide use during pregnancy and lactation.
