Therapy for Head Lice

To the Editor.—
I am writing because of concern about the article "Therapy for Head Lice Based on Life Cycle, Resistance, and Safety Considerations."1 My first concern is the recommendation to use malathion, an organophosphate pesticide, as the first-line therapy when permethrin is also recommended by the American Academy of Pediatrics Committee on Infectious Diseases for this purpose.2 As an organophosphate, malathion is in the class of pesticides that includes chlorpyrifos, which has now been banned as a home-use pesticide. Malathion is also not recommended for children <6 years of age. Thus, malathion has a greater possibility for toxicity than permethrin.3,4 Under these circumstances, it would seem reasonable to use permethrin unless treatment failure is documented.
My second concern is that the third author of this article serves as vice president of and is a major shareholder in the sole pharmaceutical company that manufactures and markets Ovide, a product that is 0.5% malathion and is recommended in this article as the first-line therapy for head lice in children. The conflict of interest is obvious and should have resulted in more than just listing the author's statement in very small print under the location of the authors place of employment.
