Gamma Benzene Hexachloride Lotion (USP/IP)
Gamma Benzene Hexachloride is primarily used for treating infestations of scabies mites (Sarcoptes scabiei) and lice. It belongs to the organochlorine class of medications and works by overstimulating the parasite’s nervous system, leading to its destruction. Due to its toxicity profile, it is generally considered a second-line treatment when safer alternatives are ineffective or unsuitable.
Clinical Indications
Scabies Management: Eradicates mites and their eggs from the skin surface.
Pediculosis: Effective in treating head lice and pubic lice infestations.
Secondary Prevention: Helps prevent reinfestation within households when used appropriately.
Methods of Application
To ensure effectiveness and safety, follow instructions carefully:
For Scabies:
Preparation: Take a lukewarm bath and dry thoroughly. Allow the body to cool before application.
Application: Apply a thin layer from neck to soles, focusing on skin folds, between fingers, and under nails.
Duration: Leave on for 8–12 hours (preferably overnight).
Removal: Wash thoroughly with warm, soapy water.
For Head Lice:
Apply sufficient lotion to dry hair and scalp.
Leave for 4 minutes only.
Add water to form a lather and rinse thoroughly.
Use a fine-toothed nit comb to remove dead lice and eggs.
