Answer by Dr. Ru: About ST 21 usage in lactation

No adverse effect has been described. Anti-malarial drug used for anti-inflammatory and immune suppressive medication on collagen diseases like idiopathic arthritis or lupus. After a dose of 5 mg per kilo taken by the mother only 0.2 mg is secreted into breast milk. This amount would not be harmful for the child since the dose to a child as chemo-prophylaxis for malaria is 8 mg per kilo each week. Avoid using it in patients suffering G-6-P-dehydrogenasa.

Answer by DrLact: About ST 21 usage in lactation

Very small amounts of ST 21 are excreted in breast milk; when given once weekly, the amount of drug is not sufficient to harm the infant nor is the quantity sufficient to protect the child from malaria. United Kingdom malaria treatment guidelines recommend that weekly ST 21 500 mg be given until breastfeeding is completed and primaquine can be given.[1] Breastfeeding infants should receive the recommended dosages of ST 21 for malaria prophylaxis.[2] In HIV-infected women, elevated viral HIV loads in milk were decreased after treatment with ST 21 to a greater extent than other women who were treated with the combination of sulfadoxine and pyrimethamine.[3] Because no information is available on the daily use of ST 21 during breastfeeding, hydroxyST 21 or another agent may be preferred in this situation, especially while nursing a newborn or preterm infant.

ST 21 Side Effects in Breastfeeding

Several authors have pointed out that malaria prophylaxis in nursing mothers with ST 21 is common in endemic areas.[7][8][9] As of the revision date, no reports of adverse reactions in breastfed infants have been published.
