Ivermectin Lotion 0.5% BP is a topical medication used for the treatment of head lice infestations in people aged 6 months and older. It is effective, convenient, and usually works with a single application, making it suitable for children and adults.
What is Ivermectin Lotion 0.5% BP?
Ivermectin is an antiparasitic medication that targets lice. Unlike traditional lice shampoos, this lotion:
Acts directly on lice, causing paralysis and death.
Prevents new lice emerging from nits (eggs) from surviving.
Reduces the need for repeated treatments.
It is not intended for children under 6 months, and it should only be applied externally.
How Does It Work?
Ivermectin binds to nerve and muscle cells of lice, causing:
Paralysis of the lice, preventing them from feeding.
Death of the lice within hours.
While it does not directly kill nits, any lice that hatch from the nits will die, breaking the infestation cycle.
Clinical studies show that 71–76% of patients are lice-free after a single 10-minute application.
