<p>There are no adequate and well‐controlled studies in pregnant women of the effect of bupivacaine hydrochloride on the developing fetus. Bupivacaine should not therefore be given in early pregnancy only if the potential benefit justifies the potential risk to the fetus. Bupivacaine enters the mother&#39;s milk, but in such small quantities that there is no risk of affecting the child at therapeutic dose levels.</p>
