Evidence selection
This evidence summary included randomised controlled trials (RCTs) that investigated the efficacy of oral ivermectin for scabies. Because no RCTs were identified that had investigated the efficacy of oral ivermectin for crusted scabies, uncontrolled trials and case series with 4 or more participants with crusted scabies that reported cure rates or treatment failures were included. There are also reports in the literature about using oral ivermectin to treat outbreaks of scabies in mass care settings, such as nursing homes. However, only 1 study met the inclusion criteria for the review.
