Isopropyl myristate (Resultz) is available in Canada and Europe, but not in the United States (it is currently in phase III clinical trials). It is a non-insecticide–based drug that contains isopropyl myristate, an ingredient commonly used in cosmetics. Its mode of action is a mechanical process that weakens the waxy shell of lice, resulting in internal fluid loss and dehydration. [36]
