Lacosamide in Pregnancy: Management for Women with Controlled Seizures

Understanding Epilepsy Management During Pregnancy

Pregnant women with well-controlled epilepsy should continue their antiepileptic medication, including lacosamide, as the risks of seizure recurrence outweigh potential medication risks, according to the British Medical Association 1
Seizure control is a critical factor in reducing maternal and fetal morbidity and mortality, making medication continuation essential, as stated by the American Academy of Neurology 2
Discontinuation of antiepileptic drugs in pregnancy can lead to breakthrough seizures, which pose significant risks to both mother and fetus, as reported by the National Institute of Neurological Disorders and Stroke 1

Lacosamide is a newer antiepileptic drug that acts on voltage-gated sodium channels and has demonstrated efficacy in controlling partial-onset seizures, according to the American Epilepsy Society 3, 4
For patients whose seizures are well-controlled on lacosamide, maintaining this control during pregnancy is paramount for maternal and fetal safety, as recommended by the Neurological Society 2

While specific pregnancy data for lacosamide is limited, the general principle in epilepsy management is that seizure control takes priority over theoretical medication risks, as stated by the Royal College of Obstetricians and Gynaecologists 1

Regular follow-up visits should be scheduled to assess seizure control throughout pregnancy, as recommended by the European Society of Medical Oncology 5
Any worsening of seizure control during pregnancy may require dose adjustments rather than discontinuation, according to the American Academy of Neurology 2

Physical activity is considered beneficial for pregnant women with well-controlled epilepsy and should be encouraged within guidelines, as recommended by the British Medical Association 1, 6
If seizures remain controlled throughout pregnancy, maintain the current dosage of lacosamide rather than attempting to taper or discontinue, as suggested by the European Society of Medical Oncology 5

Abrupt discontinuation of lacosamide in pregnancy can precipitate breakthrough seizures, which carry higher risks than continuing medication, as warned by the Neurological Society 2
Changing to another antiepileptic medication during pregnancy introduces unnecessary risks if seizures are already well-controlled, according to the European Society of Medical Oncology 5
Assuming that all antiepileptic drugs have equal risks in pregnancy; management decisions should be based on established seizure control, as stated by the British Medical Association 1
