Ivermectin is a broad-spectrum antiparasitic medication used in humans to treat a variety of parasitic infections. It is commonly prescribed for conditions such as strongyloidiasis , onchocerciasis , scabies, head lice, and other infestations caused by parasites. Ivermectin for humans works by binding to specific ion channels in the nerve and muscle cells of parasites, leading to paralysis and death of the organisms, while having minimal effect on human cells at prescribed doses. The medicine is usually taken orally as a tablet, with the dosage determined by a person’s body weight, age, and the type of infection being treated. In some cases, topical formulations are also used, especially for skin conditions like scabies or lice. When taken as directed, ivermectin is generally safe and well tolerated. Common side effects may include nausea, dizziness, diarrhea, or mild skin reactions, while serious side effects are rare. Ivermectin should only be used under the guidance of a qualified healthcare professional. It is important to note that ivermectin is not approved for treating viral infections, and misuse or excessive dosing can lead to serious health risks. Proper medical advice ensures safe and effective treatment.
