What It Is and How It Works

Ivermectin is an antiparasitic agent that belongs to the avermectin class of drugs. It works primarily by binding to certain chloride channels specific to invertebrate nerve and muscle cells. This binding leads to an increased flow of chloride ions, which results in paralysis and eventual death of the parasite.

Though highly effective against parasites, ivermectin does not typically affect humans in the same way due to differences in the nervous systems of humans and the parasites it targets. However, caution is still necessary due to potential side effects and interactions.

Indications / Uses

Oral ivermectin is commonly prescribed for:

Onchocerciasis: Also known as river blindness, this is a parasitic disease caused by Onchocerca volvulus.
Strongyloidiasis: An infection caused by the roundworm Strongyloides stercoralis.

There has been interest in possible off-label uses, such as for certain viral infections, but such applications remain controversial and should only be considered under healthcare supervision.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in oral tablet form, typically prescribed based on body weight. The usual dosing is a single dose, but treatment duration and dosage may vary depending on the specific infection or condition being treated.

Factors influencing dosing include:

Age and Weight: Dosing is often weight-based, especially in pediatric and adult patients.
Liver and Kidney Function: Impaired function may require dosage adjustments, supervised by a healthcare provider.
Pregnancy/Breastfeeding: Use during pregnancy and lactation involves weighing potential risks and benefits.

It\’s crucial to follow prescription instructions and discuss any concerns with your healthcare provider.
