only be given to you if your doctor
considers that the benefit of treatment
outweighs the risk to the developing
baby or new-born baby.
Lidocaine is excreted in breast milk, so
if you are breastfeeding, your doctor or
nurse will observe your baby for any
side effects.

The band is kept in place for at least
