Introduction Scabies is a highly contagious skin disease caused by an ectoparasite mite called Sarcoptes scabiei. Ivermectin and permethrin have been commonly used for the treatment of scabies. However, topical ivermectin has been compared to other treatment modalities to a lesser extent. Objective This study aimed to compare the efficacy of topical ivermectin versus topical permethrin in the treatment of uncomplicated scabies. Methods 354 patients with scabies attending the dermatology outpatient department of Pak Emirates Military Hospital Rawalpindi were enrolled. Patients were divided into two groups randomly. The first group and their family contacts received 1% ivermectin lotion whereas the other received 5% permethrin lotion. Patients were evaluated at the end of the second and the fourth week. Results At the end of the second week, initial follow-up showed that 97 out of 159 patients (61.0%) in the ivermectin 1% group, and 107 out of 159 patients (67.3%) in the permethrin 5% group had achieved clinical cure (P=0.24). On the final follow-up at the end of Week 4, the cure rate amounted to 85.5% (136 of 159 patients) in the ivermectin group and 89.9% (143 of 159 patients) in the permethrin group. Differences among both groups remained statistically insignificant (P=0.23). Conclusions The use of ivermectin 1% versus permethrin 5% as topical therapy showed almost identical results for the treatment of uncomplicated scabies. Side effects were minimal and there were no significant differences observed in patients with regard to compliance among both the groups.
