Quick Facts Scannable

• Ivermectin is used primarily to treat parasitic infections.
• It works by paralyzing and killing parasites in the body.
• Available in tablet and topical forms for humans.
• Pregnancy and breastfeeding require caution and physician input.
• Common side effects include dizziness and nausea.
• May interact with blood thinners and other medications.

What It Is and How It Works

Ivermectin is an antiparasitic agent that belongs to the class of drugs known as avermectins. It exerts its effect by binding to glutamate-gated chloride channels in the parasites, leading to an increase in the permeability of the cell membrane to chloride ions. This increase causes paralysis and death of the parasite. This mechanism makes ivermectin effective against a wide range of parasites.

Indications / Uses

Primarily, ivermectin is prescribed for the treatment of certain parasitic infections such as:

• Onchocerciasis: Also known as river blindness.
• Lymphatic filariasis: A condition known for causing severe swelling.
• Strongyloidiasis: Caused by the nematode Strongyloides stercoralis.
• Scabies: Often used off-label for resistant cases under medical guidance.

Off-label uses should be supervised by clinicians due to variable evidence and safety concerns.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in various forms:

• Tablets: Commonly used for systemic infections.
• Creams: Used typically for skin conditions like scabies.

Dosage depends on the type of infection and patient-specific factors such as age, weight, kidney function, and concurrent medications. It is crucial to follow the prescribing clinician\’s instructions, as these factors significantly affect dosing decisions.
