What It Is and How It Works
Ivermectin is an antiparasitic agent that targets the nervous system of lice, resulting in paralysis and death. The lotion form is applied directly to the scalp and hair, ensuring direct contact with the lice and their larvae. It does not require nit combing to remove dead lice, making it a convenient option for parents and caregivers.
Mechanistically, ivermectin affects chloride ion channels in the nervous system of the lice, which are critical for neurotransmission. The disruption of these channels leads to paralysis and eventual death of the parasite.

Ivermectin lotion is primarily indicated for the treatment of head lice infestations. It is considered effective even in cases where resistance to other treatments may occur. The lotion is beneficial for adults and children aged 6 months and older who are affected by head lice, providing relief by killing lice without the need for extensive combing.

Ivermectin is available in the form of a lotion that is applied topically. Typically, the lotion is used as a single application to dry hair and scalp.
