In Nordic countries and North America, a permethrin formulation for lice treatment is marketed under trade name Nix, available over the counter. [[Johnson & Johnson]]'s UK brand Lyclear covers an assortment of different products, mostly non-insecticidal, but a few of which are based on permethrin.<ref>{{cite web|url=https://www.lyclear.co.uk/products/head-lice-treatments/|website=Lyclear UK|title=Head Lice Treatments|access-date=24 September 2018|archive-date=25 September 2018|archive-url=https://web.archive.org/web/20180925025411/https://www.lyclear.co.uk/products/head-lice-treatments/|url-status=live}}</ref>

Stronger concentrations of permethrin are used to treat scabies (which embed inside the skin), compared to lice (which remain outside the skin). In the U.S. the more concentrated products such as Elimite are available by prescription only.<ref name="Elimite FDA label" /><ref>{{cite web|url=https://www.cdc.gov/scabies/hcp/clinical-care/ |website=U.S. [[Centers for Disease Control and Prevention]] (CDC) |title=Resources for Health Professionals: Scabies Medications|date=19 April 2019|access-date=24 September 2018|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430075605/http://www.cdc.gov/parasites/scabies/health_professionals/meds.html|url-status=live}}</ref>
