Artemether and Lumefantrine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Artemether and lumefantrine have not been studied in nursing mothers. Estimates of its excretion into breastmilk indicate that amounts in milk are very low. The Centers for Disease Control and Prevention consider the drug combination acceptable for use in mothers nursing an infant weighing at least 5 kg (11 pounds) and it can be given directly to infants weighing 5 kg or more.[1] The safety of the combination in breastfed infants under 5 kg is not known. Tablets can be crushed and administered in breastmilk to enhance absorption in small infants.[2]

Drug Levels

Maternal Levels. The excretion of artemether and lumefantrine in breastmilk was estimated from average maximum serum concentrations after a standard 6-dose regimen of artemether 40 mg and lumefantrine 240 mg daily, assuming a M/P ratio of 1.04 for artemether and 1.3 for lumefantrine. The authors estimated that a fully breastfed infant would receive 0.03 mg daily of artemether or less than 0.4% of the recommended dose for a 5 kg infant, and 5 mg daily of lumefantrine or less than 10% of the recommended dose for a 5 kg infant.[3]
