Head Lice and Scabies

 

Concerns about emerging resistance and the potential harm of using permethrins have prompted a search for effective pediculicidal therapies that are not harmful to children with repeated use. An herbal formulation has been shown to be effective for head lice. Ivermectin can also be compounded for topical application or as an oral dose titrated for each patient for the treatment of head lice and scabies.

Twenty six male and female patients aged 5 to 17 years had head lice infestation confirmed by eggs presence and received treatments with a single 200 microgram/kg oral dose of. At day 14 after treatment, 20 had 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 appeared clear of infestation (27%), but 4 of the 6 patients with no eggs 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 may be appropriate.

Two hundred scabies patients were randomly allocated to receive either oral ivermectin in a single dose of 200 micrograms/kg body weight, or 1% lindane lotion for topical application overnight. Patients were assessed after 48 hours, two weeks and four weeks. After a period of four weeks, 82.6% of the patients in the ivermectin group showed marked improvement; only 44.44% of the patients in the lindane group showed a similar response. Oral ivermectin is easy to administer as a single oral dose, induces an early and effective improvement in signs and symptoms, and compliance is accordingly increased.
