Lindane is a chlorinated insecticide used as an ectoparasiticide and ovicide in the treatment of scabies, Pediculosis humanis capitis (lice) and Phthirus pubis (crab lice). Dermatological topical application.

It is very fat soluble, is very well absorbed through the skin and is commonly found in food and breast milk.

Application of a 0.3% lindane lotion to the entire skin of a nursing mother for 24 hours raised lindane levels in milk 20 to 70 times baseline levels in the following days. (Senger 1989).

May behave as an endocrine disruptor, as it has estrogenic activity. (Massart 2005)

During breastfeeding safer alternatives are preferable. (Workowski 2021, Thomas 2020, Butler 2014)

It is considered a persistent environmental contaminant. Topical medications containing lindane have been withdrawn from the market in many countries. (Schaefer, 2015).

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.
