Efficacy of ivermectin for the treatment of head lice (Pediculosis capitis)

Trop Med Parasitol. 1994 Sep;45(3):253-4.


Twenty six male and female patients aged 5 to 17 years who had head lice infestation confirmed by eggs presence and received treatments with a single 200 mu/kg oral dose of ivermectin in open fashion. At day 14 after treatment, 20 responded to the treatment (77%), and 6 patients (23%) presented with a complete disappearance of eggs and all clinical symptoms. At day 28, 7 patients were healed (27%), but 4 patients of the 6 healed at day 14 presented with signs of reinfestation. This study suggests that ivermectin is a promising treatment of head lice, and a second dose at day 10 should be appropriate for a further comparative trial.
