Summary
Successful pregnancy outcomes were achieved in 88% of women with epilepsy. Despite changes in anticonvulsant prescribing, monotherapy remains crucial for managing epilepsy during pregnancy to minimize risks.
Area of Science:
- Neurology
- Obstetrics
- Pharmacology
Background:
- Epilepsy affects women of reproductive age, necessitating careful management during pregnancy.
- Anticonvulsant drug use during pregnancy presents risks for both mother and fetus.
Purpose of the Study:
- To analyze changes in anticonvulsant prescribing patterns and pregnancy outcomes in women with epilepsy over two decades.
- To evaluate the effectiveness of monotherapy versus polytherapy in pregnant women with epilepsy.
Main Methods:
- Retrospective analysis of 348 pregnancies in 207 women with epilepsy.
- Data collected from two distinct periods: 1977-1981 and 1987-1991.
- Comparison of anticonvulsant drug choices, including monotherapy and polytherapy, and recorded pregnancy outcomes.
Main Results:
- Overall successful pregnancy outcome in 88% of cases.
- Shift in prescribing from phenobarbitone and phenytoin to carbamazepine and sodium valproate.
- 24% of patients in the later cohort received multiple anticonvulsants, despite a trend towards monotherapy.
- No significant reduction observed in congenital malformations (4.8%), spontaneous abortions (6.9%), or low birth weight babies (9.4%).
Conclusions:
- Monotherapy is vital for managing epilepsy in pregnant women, especially until newer agents are well-established.
- Continued vigilance and research are needed to optimize anticonvulsant therapy for pregnant women with epilepsy.
- While prescribing patterns evolved, achieving better fetal outcomes requires further investigation beyond drug choice alone.
