Infants exposed to hydroxychloroquine during breastfeeding receive only small amounts of the drug in breastmilk. In infants up to at least 1 year of age, careful follow-up found no adverse effects on growth, vision or hearing.[1-3] International experts indicate that hydroxychloroquine is acceptable during breastfeeding.[4-7]
When given once weekly for malaria prophylaxis, the amount of drug is not sufficient to harm the infant nor is the quantity sufficient to protect the child from malaria. Breastfeeding infants should receive the recommended dosages of hydroxychloroquine for malaria prophylaxis.[8]
