What It Is and How It Works
Ivermectin is an anti-parasitic agent that works by binding to specific proteins within the parasites. This binding increases the permeability of cell membranes to chloride ions, effectively paralyzing and subsequently killing the parasites. Despite this action, it does not cross the blood-brain barrier in humans, minimizing the risk of adverse effects on the host.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections such as:
- Onchocerciasis: Caused by the parasite Onchocerca volvulus and is often referred to as river blindness.
- Strongyloidiasis: An infection caused by the Strongyloides stercoralis roundworm.
Off-label uses include treatments for scabies and chronic strongyloidiasis, although these should only be pursued under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablet form for human use. Dosage is typically based on body weight and the type of infection being treated. It is crucial to follow the healthcare provider\’s instructions and the prescription label, as dose adjustments may be necessary depending on factors such as liver function, kidney function, and coexisting medical conditions.
How to Take It Correctly Step-by-Step
Ivermectin should be taken on an empty stomach with a full glass of water. It\’s essential to adhere to the prescribed dosage schedule. If a dose is missed, it should be taken as soon as remembered unless it\’s near the time of the next dose, in which case, skip the missed dose. Never double doses. Store ivermectin in a cool, dry place away from moisture and heat.
