Safe substance and/or breastfeeding is the best option.

Permethrin is a pyrethroid insecticide. It is used in the treatment of head lice, pubic lice and in the treatment and prevention of scabies. Topical cutaneous application.

Permethrin is also used in veterinary medicine and as an agricultural, horticultural and domestic insecticide and disinsecticide of premises,  and as an insecticide of mosquitoes, flies and larvae in the control of malaria, onchocerciasis and tsetse flies.

Permethrin is found in milk samples from women in regions where it is widely used for agricultural or malaria control purposes. However, the limits are below those permitted by WHO. (Pedersen 2021, Feo 2012, Corcellas 2012, Weldon 2011, Sereda 2009, Bouwman 2009 & 2006, Zehringer 2001)

Absorption through the skin is negligible. (Butler 2014)

No problems have been observed in infants whose mothers used permethrin. (Ito 1993)

Authorized use in young infants. (Salavastru 2017)

Expert authors consider it safe during lactation (Workowski 2021, Salavastru 2017, Butler 2014, Leachman 2006, Porto 2003). WHO 2002 essential medicines list: compatible with breastfeeding. (WHO 2002)

Permethrin is considered the treatment of choice for scabies in nursing mothers. (CDC 2002)

Do not apply to the breast or clean thoroughly before breastfeeding. Keep hair short or tied back so that the infant cannot suck on it.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
