Drug Levels and Effects
Summary of Use during Lactation
Information in this record refers to the use of (14C)-glycocholic acid as a diagnostic agent. Breastfeeding does not need to be suspended after administration of (14C)-glycocholic acid.[1,2]
Drug Levels
Carbon 14 is a low-energy beta emitter with a physical half-life of about 5730 years. (14C)- glycocholic acid has an effective half-life of 143 hours. Approximately 9.2% of the injected radioactivity is excreted into breastmilk.[1]
