Ivermectin 3 mg tablets are commonly used to treat parasitic infections such as strongyloidiasis (intestinal threadworm) and onchocerciasis (river blindness). They work by paralyzing and killing the parasites, halting their spread and allowing the body to eliminate them. Additionally, ivermectin is sometimes prescribed off-label for conditions like scabies or lice infestations. The medication is typically taken on an empty stomach with water for optimal absorption. Always follow your doctor’s prescription to ensure safe and effective use. Regular monitoring may be needed to track treatment progress, especially for more severe or systemic infections.
