[Abstract] Antiepileptic drug treatment during pregnancy and delivery in women with epilepsy – A retrospective single center study

Highlights

Pregnancies in women with epilepsy (WWE) increased significantly during our 11-year study period (41% increase).

Twelve different AEDs were prescribed to WWE during pregnancies in the 11-year period investigated (2005-2015) with Lamotrigine (36.1%), Carbamazepine (25.0%), and Valproic Acid (13.5%) most commonly used.

Valproic acid use was markedly reduced comparing the years 2005-2010 (18.4%) and 2011-2015 (9.4%), a reduction of 48%.

Unfortunately, a trend towards an increase in treating WWE with more than one AED was observed.

Purpose

Antiepileptic drugs (AED) are among the most common teratogenic drugs prescribed to women of childbearing age. During pregnancy, the risk of seizures has to be weight against the use of AED treatment. Primary goal was to observe and describe AED treatment policy and its changes during an eleven-year period at our third referral center.

Methods

We scrutinized the medical health records for all cases of female epileptic patients admitted for labor at the Rabin Medical Center during the years 2005 – 2015.

Results

A total of 296 deliveries were recorded with 136 labors occurring in the period 2005-2010 (22.7/y) and 160 in 2011-2015 (32.0/y; increase of 41%). Twelve different AEDs were prescribed to WWE during pregnancies in the 11-year period investigated (2005-2015). Most commonly used AEDs during pregnancy were Lamotrigine (36.1%), Carbamazepine (25.0%), and Valproic Acid (13.5%). Comparing their use during the years 2005-2010 and 2011-2015, Lamotrigine (35.3% vs. 36.9%) and Carbamazepine use (23.5% vs. 26.0%) increased slightly. Valproic acid use was markedly reduced in the second period: 18.4% in the years 2005-2010 lowered to 9.4% during 2011-2015, a reduction of 48%. Unfortunately, a trend towards an increase in treating WWE with more than one AED was observed.

Conclusions

The proportion of WWE treated with VPA during pregnancy was significantly reduced in the observed period (2005-2015). Change in fetal outcome during this period for WWE could not be detected.
