Head Lice Update

Ivermectin may be more effective than malathion lotion in killing head lice.
The Los Angeles Times (3/11, Stein) reports, "A new study has found that in tough cases" of head lice, Stromectol (ivermectin), which is "not approved for use in the US for head lice," eradicates the "parasites more effectively than" a lotion containing the insecticide malathion. "The study, published Thursday in the New England Journal of Medicine," studied "812 people in 376 households in seven areas in the world," and found that in the "ivermectin group, 95% of the participants were lice-free after two weeks, compared with 85% of the malathion group." The Times adds, "Ivermectin is not approved for use in the US for head lice."
Bloomberg News (3/11, Ostrow) points out that "those in the medical trial were considered hard to cure because they had been treated unsuccessfully with lotions for their head lice for two to six weeks before the start of the study." The researchers also "said the medicine should be restricted to people whose head lice doesn't go away with other treatments to prevent resistance to the drug." HealthDay (3/10, Gordon), MedPage Today (3/10, Emery) and WebMD (3/10, DeNoon) also covered the story.
