What It Is and How It Works

Commonly available as a 0.5% lotion, ivermectin is applied topically. The lotion should cover the entire scalp and dry hair. Usual pediatric and adult instructions involve a single application, sometimes repeated after a week as recommended by a healthcare provider. Dosing can vary based on factors such as age, weight, and severity of infestation, emphasizing the need for tailored healthcare guidance.
