What It Is and How It Works

Ivermectin is an antiparasitic agent that works by interfering with the nervous system of parasites, leading to their paralysis and death. It binds to specific ion channels in the nerve and muscle cells of parasites, disrupting their neurological activity. This mechanism is highly effective in eradicating a range of parasitic worms and insects.

Indications / Uses

Ivermectin is approved for treating several parasitic infections, including:

Onchocerciasis (River Blindness): Caused by the worm Onchocerca volvulus, leading to severe itching and eye damage.
Lymphatic Filariasis: Affects the lymphatic system, causing swelling and tissue damage.
Strongyloidiasis: Infection by the intestinal worm Strongyloides stercoralis.
Scabies: A skin infestation caused by the mite Sarcoptes scabiei.

Off-label uses include treatment for head lice, certain viral infections, and more, but these should be pursued only under professional guidance due to limited evidence.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several formulations, including tablets, topical creams, and injectable solutions. Dosage is typically based on body weight, the severity of the infection, and specific patient factors such as age and renal or hepatic function. It is crucial to follow the prescription label and healthcare provider’s guidance for safe and effective use.

When taking ivermectin, adhere to the following guidelines:

Take oral forms on an empty stomach with water.
Avoid taking more than prescribed; do not double doses if one is missed.
