Head Lice Infestations NATROBA was studied in two randomized, active-controlled trials (N=552) in subjects with head lice; Table 1 presents selected adverse events, regardless of relationship to NATROBA, that occurred in at least 1% of subjects. Table 1: Selected Adverse Events Occurring in at least 1% of Subjects with Head Lice Infestation Signs Natroba (N=552) Permethrin 1% (N=457) Application site erythema 17 (3%) 31(7%) Ocular erythema 12 (2%) 15 (3%) Application site irritation 5 (1%) 7 (2%) Other less common reactions (less than 1% but more than 0.1%) were application site dryness, application site exfoliation, alopecia, and dry skin.

Subjects received a single application of NATROBA to the skin from the neck to the soles of the feet, which was washed off after a minimum of 6 hours. Table 2 presents adverse reactions related to NATROBA treatment that occurred in at least 1% of subjects.
