Is Vanquish safe while breastfeeding?

The Vanquish is for body shaping and circumferential reduction of abdomen and thighs. It uses Selective RF (radio frequency) technology that targets the largest treatment area in a single session. Due to the use of RF, I would not recommend continuing to Vanquish until you are done breastfeeding. That should have been one of the things your provider covered with you beforehand. 

Vanquish is not recommended while breastfeeding.  I would discontinue your treatment until you are no longer breast feeding, and I would recommend letting your pediatrician know.
Congratulations on your new baby.

Hi,Most likely you haven't caused harm to your babies but Vanquish is not recommended during pregnancy and nursing.  I would talk to your provider about finishing your series after you stop nursing.Warmly,Dr.Liu
