What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitic agents. It works by binding to specific channels in the nerve and muscle cells of parasites, causing paralysis and death of the parasites. This mechanism effectively treats infections caused by various parasites.
At a more technical level, ivermectin enhances the release of gamma-aminobutyric acid (GABA), which contributes to the paralysis effect in parasitic organisms.
Indications / Uses
Ivermectin is primarily used for treating several types of parasitic infections in humans, such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal worms)
- Scabies
- Pediculosis (lice)
Additionally, certain formulations of ivermectin, such as the 500ml option, are utilized in veterinary medicine for the treatment of parasites in animals like cattle and horses. It is important to use the medicine according to the specific type of species it is meant for, under veterinary guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin can be found in several dosage forms, including:
- Oral tablets
- Topical creams

The typical dose and formulation depend on the type of infection being treated and may vary significantly between human and veterinary applications. Adjustments to dosage might be necessary for special populations such as children, the elderly, or those with liver/kidney impairments.
