Iverheal 6 mg is another formulation of the medication containing Ivermectin, but with a lower dose compared to Iverheal 12 mg. Ivermectin works by binding to specific channels in the nerve and muscle cells of parasites. This binding disrupts their neuromuscular function, leading to paralysis and death of the parasites. Dosage is often based on body weight. For adults, a common dose is 150-200 mcg/kg for onchocerciasis, which would require multiple 6 mg tablets depending on body weight.
