What It Is and How It Works
Ivermectin is an anthelmintic, meaning it targets parasitic worms. It works primarily by binding to specific chloride channels in nerve and muscle cells of parasites, leading to paralysis and death of these organisms. By doing so, it effectively eliminates the parasitic infection.
Initially developed and approved for animals, its formulation for human use has been pivotal in eradicating or controlling human parasitic diseases, most notably onchocerciasis, also known as river blindness, and lymphatic filariasis.
Indications / Uses
Ivermectin is primarily used to treat:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Scabies and lice infestations
Some off-label uses are monitored under strict medical supervision, especially in areas with limited access to alternative treatments. One controversial off-label use has been for COVID-19, a use not recommended by major health organizations without further conclusive studies.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human use commonly comes in oral tablets. Veterinary formulations can be topical or injected, but these are not suitable for human use.
Dosing typically depends on body weight and the condition being treated. The decision on dosing is impacted by several factors, including age, kidney and liver function, and co-morbid conditions. It is crucial to follow the prescribed dosage by a healthcare professional, as misuse can lead to toxicity or ineffective treatment.
