Is 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline? Is 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline safe for nursing mother and child? Does 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline extracts into breast milk? Does 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline has any long term or short term side effects on infants? Can 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline influence milk supply or can 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline decrease milk supply in lactating mothers?

Information in this record refers to the use of 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline as a diagnostic agent. No information is available on the use of 4-((1E)-2-(4-(2-(2-(2-((sup 18(f))fluoroethoxy)ethoxy)ethoxy)phenyl)eth-1-en-1-yl)-N-methylaniline during breastfeeding. The manufacturer recommends withholding breastfeeding for 24 hours after a diagnostic dose Twenty-four hours is about 10 half-lives of fluoride F 18 and less than 0.01% of the radioactivity administered will remain in the body. The mother can nurse just before administration of the radiopharmaceutical. If the mother has expressed and saved milk prior to the examination, she can feed it to the infant during the period of nursing interruption.[1][2][3] 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 background levels they may safely resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[4]
