What It Is and How It Works
Ivermectin is an antiparasitic agent that functions by interfering with the nerve and muscle functions of parasites. Specifically, it binds to glutamate-gated chloride channels unique to invertebrates, leading to the paralysis and death of the parasite. This mechanism makes it effective against a range of parasitic worms and certain ectoparasite infestations.
Indications / Uses
Ivermectin is primarily used for treating parasitic infections such as onchocerciasis (river blindness) and strongyloidiasis. It is also used off-label for other parasitic conditions. Some have considered its use for COVID-19; however, the evidence on its efficacy and safety for this purpose remains mixed and controversial, emphasizing the need for healthcare supervision.
Dosage Forms and Typical Dosing Considerations
Commonly available as oral tablets and topical creams/lotions. Dosage depends on the condition being treated, patient weight, and other health factors. Young children, elderly patients, and those with liver impairment may require dose adjustments. It is crucial to follow healthcare professional directions and labeled instructions meticulously.
