Ivermectin 12 mg is commonly used to treat certain parasitic infections in humans, including strongyloidiasis and onchocerciasis. It works by affecting the nerve and muscle function of parasites, leading to their paralysis and elimination from the body. The medication is usually taken as a single dose or as directed by a healthcare professional, depending on the condition. It may also be used in some cases for scabies or lice under medical supervision. Proper diagnosis, correct dosage, and adherence to medical advice are essential to ensure safe and effective treatment outcomes.
