Pseudoresistance to permethrin in scabies
Reports of permethrin resistance of Sarcoptes scabiei var. hominis are emerging. We propose that this may be pseudoresistance. The resistance is due to inadequate counselling by physicians, incorrect treatment (insufficient quantity of permethrin; too short length of treatment), and poor adherence...

Reports of permethrin resistance of Sarcoptes scabiei var. hominis are emerging. We propose that this may be pseudoresistance. The resistance is due to inadequate counselling by physicians, incorrect treatment (insufficient quantity of permethrin; too short length of treatment), and poor adherence and compliance by patients. Other reasons include single application of permethrin, suggestion to apply the drug for 6-8 hours, failed application on subungual folds, irritant contact dermatitis, in particular on genitals, for which some patients stop the treatment, and unexplainable use of permethrin in post-scabies prurigo. Thus, we believe that several cases of resistance to permethrin are actually cases of pseudoresistance.
