Levels in milk

Maternal Levels. A nursing mother was given 1 dose of sodium stibogluconate 1 gram intravenously, followed by intravenous doses of 1.4 grams (about 20 mg/kg of antimony) daily for 14 days. Numerous milk samples were obtained before and for 25 hours after the fifth and fourteenth doses of the drug. The average of the 2 trough values of antimony in milk was 0.7 mg/L; the average of the 2 peak concentrations was 3.5 mg/L at 4 hours after the dose.[ 1 ] (For comparison, average background antimony breastmilk concentrations range from 0.14 to 0.4 mcg/L).[ 2 , 3 ] After the sodium stibogluconate doses, milk antimony levels declined with a half-life of about 6 hours to a value of 0.7 mg/L at 23 hours after the dose.[ 1 ] Using the average of the peak and trough values, a fully breastfed infant would receive about 0.3 mg/kg daily of antimony or about 1.6% of the maternal weight-adjusted dosage. Infant Levels. Relevant published information was not found as of the revision date.

“No published information” means the studies do not exist yet — not that Sodium Stibogluconate is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
