Posted a picture of the little bottles of IVERMECTINA the antihelmintic sold in South America. The little bottles are 0.6% concentration and contain just 5 ml - 160 drops. The dose is one drop per one kilogram - 1,000 grs of weight. If you use the American pounds remember those are just 450 grs. The Ivermectina is produced by various companies but is is not sold in the US; it is very cheap and good medicine, used for malaria and parasitic infections!
