Full Prescribing Info
Shampoo: Kwell contains 1% w/w permethrin (10 mg/g).
Lotion: Kwell contains 5% w/w permethrin (50 mg/g).
Pharmacotherapeutic Group: Delousing agent-pyrethroid. ATC Code: P03AC04.
Pharmacology: Pharmacodynamics: The potent insecticidal action of permethrin arises from repeated depolarization of the neurons and leads to a reduction in neuronal excitability causing sensory hyperexcitability, incoordination, prostration, paralysis and eventual death.
Pharmacokinetics: Permethrin is not rapidly absorbed transdermally and that the extent of systemic exposure is very low. Plasma concentrations of permethrin are undetectable. The small amount of permethrin that is absorbed is rapidly metabolized and excreted. Distribution of the drug into major body tissues is not of great concern.
Shampoo: Treatment of head lice and their eggs and prevention for those at risk.
Lotion: Scabicide. Treatment of scabies and crab lice infestation.

Leave for 10 min before rinsing the hair thoroughly with water. Towel dry. Check any other family members and treat them if necessary to prevent re-infection.
