What It Is and How It Works
Ivermectin is an antiparasitic agent that is effective against a wide range of parasites. It works by binding to specific chloride ion channels in the nerve and muscle cells of parasites, leading to increased permeability of their cell membranes. This action causes paralysis and death of the parasites, helping clear the infection from the body.
While it is effective against parasites, ivermectin is not generally intended for viral infections such as COVID-19 unless specified by appropriate health authorities and under strict medical supervision.
Indications / Uses
Ivermectin is approved for use in treating several parasitic infections:
- Onchocerciasis: Commonly known as river blindness, this condition is caused by a worm transmitted through repeated bites by infected blackflies.
- Strongyloidiasis: An intestinal infection caused by a type of roundworm.
It may also be prescribed for off-label uses in certain circumstances, such as head lice, scabies, and certain other parasitic infections. Always use under a healthcare provider\’s guidance for off-label uses.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in oral tablet form, though topical formulations exist for other specific uses such as in veterinary medicine.
The dosage of ivermectin can vary depending on the type and severity of the infection, patient\’s weight, and medical history. For human use, tablets are typically taken orally with water, often on an empty stomach, generally as a single dose or as per a healthcare provider\’s directions.
Factors affecting dosing include:
- Kidney and liver function
- Pregnancy and breastfeeding status
- Other concurrent medical conditions
- Co-administration with other medications
Never self-prescribe; always follow directives from healthcare professionals.
