  • Lidocaine for breast biopsy and breastfeeding.

    Is there data on lidocaine given locally in the breast and breastfeeding a healthy term newborn? Can a mother breastfeed immediately after having a breast biopsy?

      No data that I know of. I would be concerned however, and would wait for a few hours after the pain returns for it to dissipate. I'd say at least 4 hours AFTER the pain has returned. This would suggest that the lidocaine has been absorbed (when the pain returns), and the 4 hours would allow a bit longer for any small amounts of lidocaine to be metabolized. But I'd be sure the drug they use IS lidocaine. They use many injectable anesthetics nowadays, some with extremely long half-lives. So be sure its lidocaine.
