Effectiveness of Topical 0.5% Ivermectin Shampoo in the Treatment of Pediculosis Capitis among School-going Female Children.

BACKGROUND

Pediculosis is a common ectoparasitic infestation in children. There are different treatment modalities that have been used in the treatment of pediculosis capitis from time immemorial, each with their own shortcomings. Increasing emergence of resistance to permethrin has led to the lookout for newer alternatives.

AIMS AND OBJECTIVES

The role of topical ivermectin in the management of pediculosis in people with culturally different hair grooming practices is analyzed in this study.

MATERIALS AND METHODS

This observational open-label clinical study was conducted in September-November 2019 in the schools that were under the rural health center at South India among school-going female children aged between 13 and 16 years of age and diagnosed with pediculosis.

RESULTS

This study demonstrated that a single application of ivermectin shampoo was able to kill head lice in 86.2% of the participants. In participants with persistent infection (13.8%), a repeat application killed the entire louse and 100% efficacy was demonstrated. Topical ivermectin is devoid of systemic side effects of oral ivermectin. Topical ivermectin has found to be more effective than contemporary recommended agents such as malathion and permethrin.
