What It Is and How It Works
Ivermectin belongs to a class of medications known as anthelmintics, primarily used to treat infections caused by certain parasites. It functions by binding to certain proteins in parasites, leading to paralysis and death of these organisms, effectively reducing their load within the body. This mechanism is particularly effective against external parasites and intestinal worms.
Indications / Uses
Ivermectin is primarily indicated for treating various parasitic infections such as:
- Onchocerciasis (River Blindness): Infection caused by Onchocerca volvulus.
- Strongyloidiasis: Intestinal infection caused by a type of roundworm.
- Scabies: A skin infestation caused by the mite Sarcoptes scabiei.
- Lice: Topical formulations may be used to treat head lice infestations.
In some regions, ivermectin has been explored for off-label uses under clinical guidance. However, it is crucial that any off-label use is managed by a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, most commonly in oral tablet form and topical preparations:
- Oral Tablets: Typical dosing is weight-based, often a single dose is effective for treating parasitic infections.
- Topical Creams/Lotions: Used for treating scabies and lice, with instructions varying based on the condition.
Dosing considerations must factor in patient-specific parameters such as age, weight, liver and kidney function, as well as potential interactions with other medications.
