What is Spinosad

Spinosad is a pediculicide mixture of spinosyn A and spinosyn D (in an approximately 5:1 ratio, respectively) used in the topical treatment of head lice in children (four years old and older) and in adults. Spinosad is an insecticide based on a compound found in S. spinosa, a bacterial species. Spinosad has also been experimented for use in cats for treatment of flea infestations, and has also been experimented for use against the KS1 Ctenocephalides felis flea strain infesting dogs, in addition to many investigations for use in other animals and agricultural plants.

Spinosad mechanism of action

Spinosad is a mixture of spinosyn A and spinosyn D in a 5:1 ratio. This combination causes neuronal hyperexcitation through mostly alteration of nicotinic acetylcholine receptors, which ultimately leads to lice paralysis and death.

Avoid getting Natroba in your eyes, mouth, or vagina. If this happens, rinse with water.

To prevent reinfection, rinse all clothing, hats, bedding, bed linen and towels in hot water and dry them in high temperature. Dry all unsuitable clothes for washing. Hair brushes, combs and hair accessories should be soaked in hot water for at least 10 minutes.

Avoid intimate contact with others until your lice infection clears up. Avoid sharing hair brushes, combs, hair accessories, hats, pillows, bedding, clothing and other personal items.
