This answer came from a question I asked in Brave search engine. Leo AI bot provided the answer. You may want to do more research.
"Ivermectin for Head Lice Ivermectin is used to treat head lice infestations in several forms, including oral tablets and topical lotions. Here's how it works and its effectiveness:
- Oral Ivermectin: Although not FDA-approved for treating head lice, oral ivermectin tablets have been shown to be effective. A single dose of 200 micrograms/kg or 400 micrograms/kg, repeated 9 to 10 days later, can kill head lice. This treatment is not recommended for children under 15 kg or for pregnant women.
- Topical Ivermectin Lotion (Sklice): This lotion, available over the counter for those 6 months and older, involves a single application of one 4-oz tube to dry hair and scalp for 10 minutes before rinsing. It kills most head lice infestations and is effective for 2 weeks after one treatment in 71 to 76% of patients. It is well-tolerated, with common side effects including ocular irritation and burning sensation of the skin.
Both treatments are effective alternatives when traditional topical treatments fail due to resistance."
