What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat a variety of parasitic infections. It works by binding to specific channels in the parasite’s cells, causing paralysis and death of the parasite. This process effectively eliminates the infection from the host’s body.
On a technical level, ivermectin binds to glutamate-gated chloride ion channels, which are vital for the parasite’s nerve and muscle functions. By disrupting these channels, ivermectin causes an influx of chloride ions, leading to paralysis and eventual death of the parasite.
Indications / Uses
Ivermectin is primarily approved for the treatment of certain parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Scabies
- Head lice
- Certain other parasitic infections
While there has been interest in off-label uses for ivermectin, particularly during the COVID-19 pandemic, such uses should only be pursued under the guidance of a healthcare professional, as evidence and guidelines may vary.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets, topical creams, and injectables. The specific form and dose depend on the type of infection being treated and the patient’s individual health factors. For oral administration, ivermectin tablets are typically taken on an empty stomach with water. The dose may vary based on the patient’s weight and the infection type.
Dosing considerations include the patient’s age, weight, liver and kidney function, and any concurrent medications or comorbid conditions. Pregnant or breastfeeding women should discuss potential risks with their healthcare provider before starting treatment.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach with a full glass of water.
- Follow the dosing schedule prescribed by your healthcare provider.
