High-dose ivermectin in malaria and other parasitic diseases: a new step in the development of a neglected drug

We highlight the absence of high-level evidence from dose-ranging studies regarding the use of oral ivermectin in susceptible parasitic diseases. We provide published data supporting the use of a higher dosage regimen of ivermectin in malaria and difficult-to-treat head lice, and announce an ongoing randomized clinical trial in severe scabies.
