Sodium Stibogluconate use while Breastfeeding

Sodium Stibogluconate Levels and Effects while Breastfeeding

Summary of Use during Lactation

Limited information indicates that maternal doses of sodium stibogluconate up to 1.4 grams daily produce low levels in milk and would not be expected to cause any adverse effects in breastfed infants,[1] especially if the infant is older than 2 months. However, if withholding nursing during therapy is elected, breastfeeding can be reinstituted 24 to 48 hours after the last dose.

Drug Levels

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.
