Is PP 557 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use PP 557? Is PP 557 safe for nursing mother and child? Does PP 557 extracts into breast milk? Does PP 557 has any long term or short term side effects on infants? Can PP 557 influence milk supply or can PP 557 decrease milk supply in lactating mothers?

Topical pyrethroid pesticide that shows activity against louses, mites and scabies.About 2% of the dose is absorbed through the skin.Do not apply it on the breast, otherwise, clean it thoroughly before feeding at the breast. PP 557 is considered the treatment of choice for scabies in nursing mothers. PP 557 is found in milk samples from women in regions in which it is used massively for agricultural purposes or malaria control. Notwithstanding, limits were found to be below those permitted by the WHO. WHO List of Essential Medicines 2002 states it is compatible with breastfeeding.

Because less than 2% is absorbed after topical application, rapid metabolism to inactive metabolites and safe application directly on infants' skin, topical PP 557 products are acceptable in nursing mothers.[1][2] Extensive exposure, such as from agricultural use or malaria control might have long-term health concerns because residues can be found in breastmilk.[3] Only water-miscible cream, gel or liquid products should be applied to the breast because ointments may expose the infant to high levels of mineral paraffins via licking.[4]

In a telephone follow-up study, 5 mothers who used PP 557 during breastfeeding reported no adverse reactions in their breastfed infants.[10]
