How Florbetaben F 18 is classified
Radiopharmaceuticals, Fluoride Radioisotopes, Diagnostic Agents
Florbetaben F 18 During Pregnancy
Florbetaben F 18 pregnancy category
Category CNote that the FDA has deprecated the use of pregnancy categories, so for some medications, this information isn’t available. We still think it’s useful to list historical info, however, given what a common proxy this has been in the past.
What we know about taking Florbetaben F 18 while pregnant
It is not known whether Neuraceq can cause fetal harm when administered to a pregnant woman or if it can affect reproduction capacity. Animal reproduction studies have not been conducted with Neuraceq. All radiopharmaceuticals, including Neuraceq, have a potential to cause fetal harm. The likelihood of fetal harm depends on the stage of fetal development and the magnitude of the radiopharmaceutical dose. Neuraceq should be given to a pregnant woman only if clearly needed. Assess pregnancy status before administering Neuraceq to a female of reproductive potential.
Taking Florbetaben F 18 While Breastfeeding
What are recommendations for lactation if you're taking Florbetaben F 18?
Information in this record refers to the use of florbetaben F 18 as a diagnostic agent. No information is available on the use of florbetaben F 18 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]
