<p>There are insufficient data on the use of Vecuronium during animal or human pregnancy to assess potential harm to the foetus. Vecuronium should be given to a pregnant woman only when the attending physician decides that the benefits outweigh the risks.<br />
<br />
<strong>Caesarean section</strong>: Studies with Vecuronium, administered in doses up to 0.1mg/kg, have shown its safety for use in caesarean section. In caesarean section the dose should not exceed 0.1mg/kg. In several clinical studies Vecuronium did not affect Apgar score, foetal muscle tonus or cardiorespiratory adaptation. From umbilical cord blood sampling it is apparent that only very little placental transfer of Vecuronium occurs which did not lead to the observation of any clinical adverse effect in the newborn.<br />
<br />
Reversal of a Vecuronium induced neuromuscular block may be inhibited or unsatisfactory in patients receiving magnesium sulphate for toxaemia of pregnancy because magnesium salts enhance neuromuscular block.Therefore, in patients receiving magnesium sulphate, the dosage of Vecuronium should be reduced and be carefully titrated to twitch response.<br />
<br />
<strong>Lactation</strong>: There are no human data on the use of Vecuronium during lactation. Vecuronium should be given to lactating women only when the attending physician decides that the benefits outweigh the risks.</p>
