Summary of use during lactation
Apazone (azapropazone) is not approved for marketing in the United States by the U.S. Food and Drug Administration. Relatively small amounts of the drug are excreted into breastmilk; however, the toxicity of the drug limits its usefulness in nursing mothers.[1] An alternate drug is preferred, especially while nursing a newborn or preterm infant.
Drug levels in milk and infant serum
Maternal Levels. Four women received apazone 600 mg intravenously within 2 hours postpartum, then twice daily for 5 to 10 days. Apazone was measured in the blood and breastmilk twice between days 4 and 6 postpartum at 4, 8 and 12 hours after the morning dose. The authors calculated that and average of 0.8 mg (range 0.2 to 1.3 mg) of apazone was excreted in milk over a 12-hour dosage interval.[2] Using reported infant and maternal body weights, a fully breastfed infant would receive an average of 2.13% (range 1.04 to 3.03%) of the mother’s weight-adjusted dosage.
