Ivermectin for humans is an antiparasitic medication widely employed to treat various parasitic infections, including intestinal worms and scabies. It operates by interfering with the nervous systems of parasites, leading to their paralysis and eventual expulsion from the body. This drug has been instrumental in combating diseases like river blindness. However, recent controversies surround its off-label use for COVID-19, with insufficient scientific evidence to support its efficacy in this context. As with any medication, it should be used only as prescribed by a healthcare professional, as misuse can result in side effects or potential interactions with other drugs.
