What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to a class of medications known as anthelmintics. It works by binding to specific channels in nerve and muscle cells of parasites, increasing the permeability of these cells to chloride ions leading to paralysis and death of the parasites. This action helps eliminate infections caused by parasites like mites and worms.
Indications / Uses
Ivermectin is primarily approved for the treatment of several parasitic infections such as:
- Onchocerciasis: Affects skin and eyes, causing severe itching and potential blindness due to the larvae of the Onchocerca volvulus worm.
- Strongyloidiasis: An infection caused by the Strongyloides stercoralis roundworm.
- Scabies and Pediculosis: Used off-label, ivermectin may treat infestations from mites and lice.
Patients with confirmed parasitic infections typically benefit from treatment. For any off-label use, clinical supervision is essential.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including tablets and topical preparations. The dosing typically depends on the type and severity of the infection, patient\’s age, weight, and other medical conditions:
- Tablets: Taken orally, often in a single dose, with water on an empty stomach.
- Topical form: Applied directly to the skin, commonly in the treatment of head lice and scabies.
Dosing adjustments may be required for elderly patients, those with liver impairment, or in the presence of other medical conditions and concurrent medications. It\’s crucial to follow healthcare professionals\’ directions.
How to Take It Correctly Step-by-Step
When taking ivermectin tablets, follow these general steps:
- Take the medication on an empty stomach, usually with water.
