Sulfiram

Sulfiram (INN) or monosulfiram, trade name Tetmosol, is an ectoparasiticide used in the treatment and prevention of scabies. It is usually sold as a solution or medicated soap, sometimes in combination with benzyl benzoate.
Sulfiram is now rarely used, but, as of 2015, is still available in Brazil, India, and South Africa (as monotherapy).
