Yes. Emilite is usually less toxic.
Yes but. There are several alternatives to using lindane, per the fda, to treat scabies and lice such as crotamiton cream & lotion, peremethrin cream & rinse, used for head and pubic lice, and Malathion lotion. These medications are recommended before patients are prescribed lindane. Is there a safer alternative to lindane? All scabicides are pesticides and must be used with caution.
