What It Is and How It Works
Ivermectin is an antiparasitic medication successfully used for treating various parasitic worm infections. In humans, it is commonly used to treat infections such as onchocerciasis (river blindness) and strongyloidiasis. In veterinary medicine, it is used to prevent and treat heartworm and acariasis, among others.
At a biochemical level, ivermectin works by binding to parts of the parasite’s nervous system, specifically the glutamate-gated chloride ion channels. This binding increases the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite.
Indications / Uses
Approved Uses
Ivermectin is approved for use in treating several parasitic infections:
- Onchocerciasis (River Blindness): Caused by the worm Onchocerca volvulus, transmitted by black flies.
- Strongyloidiasis: Caused by the roundworm Strongyloides stercoralis.
- Other Worm Infections: Such as certain types of whipworm and other minor parasitic infections.
Off-Label Uses
While ivermectin is not approved for treating COVID-19, early research and interest have prompted some off-label use. This is controversial and should only be considered with strict medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in different forms, primarily tablets for human use, and various formulations including topical creams and lotions for certain skin conditions like rosacea and lice. In veterinary contexts, formulations vary more broadly.
Typical dosing depends significantly on the specific condition being treated, the patient’s weight, and age. Patients are advised to follow prescription guidelines and not self-administer for off-label uses like COVID-19 treatment without medical approval.
How to Take It Correctly Step-by-Step
