Is enoxaparin safe to take if I'm pregnant or breastfeeding?

  • Lovenox does not cross the placenta and shows no evidence of effects on the fetus. It often is used during pregnancy as an alternative to oral anticoagulants such as warfarin (Coumadin), which cannot be safely used during pregnancy.
  • Lovenox multiple-dose vials contain benzyl alcohol as a preservative. Benzyl alcohol has been associated with a fatal "gasping syndrome" in premature neonates. Lovenox vials preserved with benzyl alcohol should be used with caution in pregnant women and only if clearly needed because benzyl alcohol may cross the placenta.
  • It is not known if Lovenox is excreted in breast milk. Since most medicines are excreted in breast milk, it is recommended that women receiving Lovenox should not breastfeed.
