What It Is and How It Works
Ivermectin is an antiparasitic medication. Its primary mechanism involves binding to glutamate-gated chloride ion channels in invertebrate nerve and muscle cells, leading to paralysis and death of the parasite. In humans, it is used to treat infections caused by parasites such as roundworms, threadworms, and other parasites. It has an impact primarily on parasites without affecting humans because these chloride channels are specific to invertebrates.
Indications / Uses
Ivermectin is primarily indicated for the treatment of a range of parasitic infections. These include:
- Onchocerciasis: Also known as river blindness, caused by Onchocerca volvulus.
- Strongyloidiasis: Intestinal infection caused by the threadworm Strongyloides stercoralis.
- Scabies and Lice: Topically applied or orally ingested for these external parasites following clinician guidance.
While ivermectin has been explored for off-label uses, these should only be pursued under direct medical supervision with clear evidence supporting such use.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including:
- Tablets: Common for systemic infections.
- Topical Cream: For skin infestations like scabies.
The dosing is usually weight-based and condition-specific. Factors like kidney or liver function, other ongoing medications, and patient age can influence dosing requirements. It is crucial to adhere to healthcare provider instructions for dosing, especially in special populations like pregnant women or those with liver disease.
How to Take It Correctly Step-by-Step
