EPILEPSY AND PREGNANCY

The management of the pregnant epileptic requires close cooperation between the neurologist and obstetrician. To prevent complications, knowledge is required about the natural history of epilepsy during pregnancy, the possible teratogenic effects of antiepileptic drugs, and changes in their absorption, biotransformation, and excretion. Close plasma antiepileptic drug monitoring is required because of the change in the handling of antiepileptic drugs during pregnancy. The treatment of status epilepticus with intravenous phenytoin is effective. Drug interactions which may lead to toxic plasma levels of some drugs and subtherapeutic plasma levels of others should be anticipated. The risk of problems resulting from antiepileptic drug therapy during pregnancy appears to be minor, provided that proper medical supervision is available. Newer antiepileptic drugs should not be administered to the pregnant epileptic until their safety in pregnancy is fully established. © 1979, Canadian Neurological Sciences Federation.
