<p data-start="140" data-end="563">Ivermectin is an antiparasitic medication that has been widely used in human medicine for several decades. Originally derived from a soil bacterium called <em data-start="295" data-end="321">Streptomyces avermitilis, the drug was developed in the late 1970s and approved for human use in the 1980s. It is considered one of the essential medicines on the World Health Organization&rsquo;s (WHO) list due to its effectiveness, safety, and impact on global health.

<p data-start="565" data-end="880">The drug works by interfering with the nerve and muscle function of certain parasites, leading to paralysis and eventual death of the organisms. Importantly, ivermectin selectively targets parasites without significantly affecting human cells, which contributes to its relatively safe profile when used correctly.

<p data-start="882" data-end="1422">Ivermectin is best known for its role in controlling two major parasitic diseases: onchocerciasis (river blindness) and lymphatic filariasis. Large-scale mass drug administration programs using ivermectin have dramatically reduced the prevalence of these conditions in many countries, preventing blindness, disability, and suffering in millions of people. Beyond these global health programs, ivermectin is also prescribed for treating other parasitic infections, such as strongyloidiasis, scabies, and certain types of lice infestations.

<p data-start="1424" data-end="1750">While ivermectin for Humans is generally well tolerated, side effects can occur. Common reactions may include dizziness, nausea, or mild skin irritation, especially when parasites are dying off in large numbers. Severe adverse reactions are rare but can happen, particularly if the drug is misused or taken without medical supervision.



<p data-start="1752" data-end="2189">Overall, ivermectin remains one of the most important tools in the fight against parasitic diseases. Its proven track record in reducing transmission, combined with ease of administration as a single oral dose, makes it invaluable for both individual treatment and community-level interventions. Continued research and responsible use will ensure that ivermectin maintains its role as a cornerstone in global parasitic disease control.
