What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to invertebrate nerve and muscle cells, causing paralysis and death of the parasites. It is often used to treat infections such as river blindness, lymphatic filariasis, and scabies. While it is effective against these parasites, its mechanism of action is not suitable for treating viral infections.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Scabies
- Lice infestations
While some have suggested its use for COVID-19, authoritative health organizations do not currently recommend ivermectin for this purpose without further evidence from clinical trials.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablet form for oral use, as well as in topical formulations for skin conditions like scabies and lice. The appropriate dose can vary based on the type of infection, the patient’s weight, and other health factors. It is crucial to follow the dosage instructions provided by a healthcare professional or on the prescription label.
