Ivermectin 6 mg tablet are primarily used to treat parasitic infections in humans. These include conditions like intestinal strongyloidiasis, caused by roundworms, and onchocerciasis (river blindness). It works by paralyzing and killing parasites, helping to reduce the infection. Ivermectin is also sometimes used off-label to treat other parasitic infections, such as scabies and head lice. Recently, it gained attention during the COVID-19 pandemic, though it is not FDA-approved for treating viral infections. Always follow a healthcare provider's advice when using ivermectin to ensure safe and effective use.
