Carbamazepine Adverse fetal effects: incidence study

The effects of in utero carbamazepine exposure were assessed retrospectively in 8 children and prospectively in 72 women who received carbamazepine during pregnancy.

Of the 8 retrospectively assessed children , 4 were exposed to carbamazepine alone, 2 to carbamazepine and phenobarbital , to carbamazepine and primidone and 1 to carbamazepine , phenobarbital and clonazepam.

Two of the 8 child ren were shown to have prenatal growth deficiency: difficulties in feeding , disorganised breathing , hypoventilation and tremulousness were observed in 3 children . Postnatal growth deficiency occurred in 3 of the 4 children followed up for > 1 year and involved a developmental quotient of 50 in 2 children and an intelligence quotient of 60 in 1 child .

Of the prospectively assessed pregnancies , 50 women took carbamazepine alone, and others received adjuvant phenobarbital and valproic acid (n = 4) , primidone (3), valproic acid (1) , ethosuximide (1) and primidone and ethosuximide (1). Carbamazepine dosage ranged from 200 to 1200 mg/day. 59% of women experienced at least 1 seizure during pregnancy. 54 infants were born live, and 48 of these were evaluated . Two children had a cleft uvula following exposure to carbamazepine and phenobarbital. Of the children exposed to carbamazepine only , 1 had a lumbosacral meningomyelocele, 1 had multiple ventricular septal defects, corrected by surgery, and 1 an indirect inguinal hernia. 5 of 25 children exposed to carbamazepine alone had delays in mental or psychomotor development. 2 of 4 children exposed to carbamazepine, phenobarbital and valproic acid exhibited delayed development .

Although the frequency of carbamazepine-induced adverse fetal effects cannot be determined from these results , they do suggest that carbamazepine ' .. . may well present a significant risk to the unborn baby'.
