Lutetium Lu 177 dotatate is a radiolabeled somatostatin analog indicated for the treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors. No information is available on the use of lutetium Lu 177 dotatate during breastfeeding. The manufacturer recommends that breastfeeding be discontinued during lutetium Lu 177 dotatate therapy and for 2.5 months following the last dose, which would usually mean permanently discontinuing breastfeeding of the current infant. Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital. When the radioactivity is at a safe level she may resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[1]
