What It Is and How It Works

Ivermectin is an antiparasitic agent used primarily to treat infections caused by certain parasites. It works by disrupting the nerve and muscle function of the parasites, ultimately leading to their paralysis and death. This action helps clear the infestation from the body.

Indications / Uses

Ivermectin is primarily used for treating parasitic infections like:

• Onchocerciasis (river blindness): A chronic parasitic infection caused by the filarial worm.
• Intestinal strongyloidiasis: A condition caused by the roundworm Strongyloides stercoralis.
• Lice and scabies: Off-label topical use is sometimes guided by healthcare providers for skin parasitic conditions.

Off-label uses should only occur under professional guidance, as they may not have the same level of efficacy or safety evidence.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several forms:

• Oral tablets: Commonly used for parasitic infections.
• Topical formulations: Used for certain skin conditions.

Dosing depends on the infection being treated, patient weight, age, and health status. Special considerations are needed for patients with liver or kidney impairment, and for pregnant or breastfeeding women. Follow the healthcare provider\’s instructions and do not self-adjust the dose.
