Primaquine use while Breastfeeding
Primaquine Levels and Effects while Breastfeeding
Summary of Use during Lactation
Little information is available on the use of primaquine during breastfeeding. If it is required, the mother and infant should be tested for G6PD deficiency before primaquine is given to a woman who is breastfeeding. United Kingdom malaria treatment guidelines recommend that primaquine be avoided in nursing mothers with malaria and that weekly chloroquine 500 mg be given until breastfeeding is completed. The Centers for Disease Control and Prevention guidelines state that primaquine may be used in breastfeeding mothers and infants with normal G6PD levels.
In general, very small amounts of antimalarial drugs are excreted in the breast milk of lactating women. Because the quantity of antimalarial drugs transferred in breast milk is insufficient to provide adequate protection against malaria, infants who require chemoprophylaxis must receive the recommended dosages of antimalarial drugs.
