Ivermectin cream for lice is a topical antiparasitic treatment used to eliminate head lice infestations effectively. It works by targeting the nervous system of lice, leading to paralysis and death of the parasites. The active ingredient, Ivermectin, is commonly prescribed in a 0.5% topical formulation for head lice. The cream is applied directly to dry hair and scalp, left on for the recommended time (usually about 10 minutes), and then rinsed off with water.
