What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat various parasitic infections. It functions by binding to the glutamate-gated chloride channels in parasites\’ nerve and muscle cells, leading to increased permeability of the cell membrane to chloride ions. This action results in the paralysis and death of the parasite. While effective against a variety of parasites, it does not usually affect humans or animals in the same way due to differences in the nervous systems.
Indications / Uses
Ivermectin is primarily approved for treating several parasitic infections such as:
- Onchocerciasis (River Blindness): Caused by the parasitic worm Onchocerca volvulus.
- Lymphatic Filariasis: Caused by infection with parasitic worms like Wuchereria bancrofti.
- Strongyloidiasis: Due to infection with the Strongyloides stercoralis parasite.
There have also been discussions about off-label uses of ivermectin for conditions not related to parasites, but such uses should only be considered under professional medical supervision due to limited and varied evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several dosage forms:
- Oral tablets: Most commonly used for human parasitic infections.
- Topical formulations: Used primarily for skin conditions like rosacea.
- Injectable forms: Primarily utilized in veterinary medicine.
Typical dosing considerations rely on the specific infection being treated, body weight, liver function, and other individual factors. It is essential always to follow a healthcare provider\’s prescription.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach, at least one hour before or two hours after a meal.
- Swallow the oral tablets whole with a full glass of water.
- If you miss a dose, take it as soon as you remember unless it\’s near the time for the next dose. Do not double doses.
