Information in this record refers to the use of sodium phosphate P 32 as a therapeutic agent. No information is available on the use of sodium phosphate P 32 during breastfeeding. The European Association of Nuclear Medicine recommends using other modalities to treat polycythemia vera and essential thrombocytopenia in patients under 60 to 65 years of age and states that the drug is contraindicated in nursing mothers.[1] If a nursing mother is given sodium phosphate P 32 systemically, breastfeeding should be discontinued permanently for this child.
