What It Is and How It Works
Ivermectin is an antiparasitic agent that targets parasites by binding to the invertebrate muscle and nerve cells, leading to paralysis and death of the parasite. It is particularly effective against a range of parasites, including those responsible for river blindness and intestinal strongyloidiasis. By immobilizing the parasites, the medication allows the body to eliminate the infestation effectively.

Off-label, it may be used in low-resource settings to treat other parasitic infections; however, such uses should only occur under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form, with 3 mg being a typical strength. Topical formulations exist for treating scabies and lice.
Dosing is individualized based on the type of infection, patient weight, and clinical response. It is crucial to follow the exact dosing instructions provided by your healthcare provider. Pregnant or breastfeeding women, older adults, and individuals with liver disease may require adjusted doses and careful monitoring.
