[Nicotine replacement therapies during pregnancy: what do we know about the balance between benefits and risks?]. / Les traitements substitutifs nicotiniques pendant la grossesse: que sait-on du rapport bénéfice-risque?

ABSTRACT

Maternal smoking during pregnancy induces obstetrical and fetal complications but also has an impact on newborns, infants, children and adults. Nicotine replacement therapies are authorized during pregnancy in France, the purpose being to reduce fetal exposure to toxic compounds in tobacco smoke. However, it is not proven that nicotine replacement therapy is harmless to the fetus and to date, no study has demonstrated any beneficial effect in terms of abstinence. It is suggested that benefit and risks of nicotine replacement therapies during pregnancy should be evaluated.
