[Follow-up of 'medications and pregnancy' at the Midi-Pyrenees Pharmacovigilance Center']

The follow-up of 283 gestations recorded by the Midi-Pyrénées Pharmacovigilance Centre concerned 544 medications, 17 solvents and 12 illicit drugs. Pregnancy outcomes were live births for 74.2 per cent of the women and voluntary (14.8 per cent), spontaneous (8.5 per cent) or therapeutic (1.8 per cent) abortions. Among the newborns, 11 had a malformation and 18 a neonatal disease. We observed an increased risk of neonatal disease for women exposed to illicit drugs during the third trimester of their pregnancy (OR = 14.28 [1.19-747.40] p = 0.0155) and for smokers (OR = 19.11 [2.11-445.00] p = 0.0011). Moreover, an increase of teratogenic risk was associated with a first trimester exposure to neurologic drugs (OR = 14.28 [2.08-100.00] p = 0.006). Women included in the present survey were more often exposed to potentially harmful drugs than the general population. However, the rates of obstetric and/or neonatal complications appear similar to those reported in France as a whole.
