How Ivermectin Works in Humans: A Scientific Overview

The remarkable efficacy of ivermectin when it comes to treating parasitic infections makes it an intriguing subject within the field of medicine. Primarily known for its use against conditions like onchocerciasis and strongyloidiasis, ivermectin is a broad-spectrum antiparasitic agent that exploits specific biological mechanisms to eliminate these pests from the human body. This medication works by binding to certain channels and receptors in the parasites, which can lead to paralysis and death of the organisms, ultimately resulting in the effective resolution of the infections they cause.

Ivermectin targets glutamate-gated chloride channels, which are present not only in invertebrate parasites but are absent in humans, lending a level of specificity to its action. By enhancing the permeability of cell membranes to chloride ions, it disrupts the neuromuscular control of parasites, thereby incapacitating them. As a result, this prevents the parasites from maintaining their position within the host and allows the immune system to eliminate them. The drug also acts on other ion channels, further debilitating the pathogens.

When determining the appropriate dosage of ivermectin, medical professionals typically base their decisions on body weight, the specific condition being treated, and individual patient factors including age and any underlying health issues. For example, the typical prescribed dose for onchocerciasis in adults is about 0.15 mg/kg, administered once every 12 months, though patients with more severe infections may require more frequent doses [[1]](https://www.drugs.com/ivermectin.html). It is crucial to adhere to established guidelines and to consult healthcare providers prior to any self-medication to avoid potential complications and ensure optimal treatment outcomes.

In recent discussions about ivermectin, especially concerning its use against viruses like SARS-CoV-2, it is important to note that while there has been exploration into its antiviral potential, current consensus in the medical community maintains that it is not approved for such applications. The FDA has emphasized that ivermectin should only be used for its specified indications, reiterating the significance of following prescribed medical guidelines to ensure patient safety and treatment efficacy [[2]](https://www.drugs.com/medical-answers/ivermectin-treat-covid-19-coronavirus-3535912/).
