Ivermectin is an antiparasitic medication that was originally developed in the late 1970s and became widely used in both human and veterinary medicine. Its primary mechanism involves binding to glutamate-gated chloride channels in the nerve and muscle cells of parasites, leading to paralysis and death of the parasite. Initially, ivermectin revolutionized the treatment of parasitic infections such as onchocerciasis (river blindness) and lymphatic filariasis, particularly in tropical regions. Its discovery was so impactful that it earned its developers, William C. Campbell and Satoshi Ōmura, the Nobel Prize in Physiology or Medicine in 2015.
Beyond its original use, ivermectin has also been effective against other parasites like scabies, strongyloidiasis, and head lice. In veterinary medicine, it’s commonly administered to prevent heartworm and treat a variety of internal and external parasites in animals. The drug’s relatively safe profile at prescribed doses has made it a staple in global health programs, especially in mass drug administration campaigns by organizations like the WHO. However, like any drug, it’s not without risks — misuse or overdosing can lead to side effects such as dizziness, low blood pressure, and, in rare cases, neurotoxicity.
In recent years, ivermectin became highly controversial due to its off-label promotion as a treatment for COVID-19. Some early laboratory studies showed antiviral activity in vitro, but these concentrations were far higher than what can be safely achieved in humans. Major health organizations, including the FDA and WHO, have reviewed the available clinical data and found no conclusive evidence supporting its effectiveness against COVID-19 in controlled, peer-reviewed studies. As a result, they advise against its use for COVID-19 outside of clinical trials. This situation highlighted the complex intersection of science, public perception, and misinformation in the digital age.
