What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat infections caused by certain types of parasitic worms and external parasites, such as lice and scabies. It works by binding to specific proteins in the parasites, causing paralysis and death of the parasites. This mechanism effectively purges these organisms from the body, relieving symptoms and preventing further spread.
Indications / Uses
The primary approved uses of ivermectin in humans include the treatment of:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal roundworm infection)
- Scabies and head lice (in topical formulations)
Additionally, ivermectin is sometimes used off-label for other conditions, under the guidance of a healthcare professional. However, public interest spiked regarding its potential use for COVID-19. It’s important to note that while some studies have explored this use, substantial evidence and regulatory approval for COVID-19 treatment are lacking in many jurisdictions.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations including oral tablets, topical creams, and lotions. The oral tablet form is commonly used for parasitic infections such as river blindness and intestinal strongyloidiasis. Topical forms are used for conditions like lice and scabies.
Typical dosing varies based on the specific indication, patient age, weight, and other medical conditions. Healthcare providers should determine the appropriate dose, especially for special populations like children, pregnant or breastfeeding women, and individuals with liver or kidney impairments.
How to Take It Correctly Step-by-Step
- Follow the dosing instructions on the prescription label or as advised by your healthcare provider.
- Take the oral form with a full glass of water, and typically on an empty stomach at least 1 hour before or 2 hours after a meal.
- If a dose is missed, take it as soon as possible unless it is close to the time for the next dose. Do not double doses.
- Store ivermectin at room temperature away from moisture and heat.
- Avoid consuming alcohol while taking ivermectin.
