What It Is and How It Works

Ivermectin is an antiparasitic medication that was developed initially to treat infections caused by certain parasites, including some types of worms, lice, and mites. It belongs to a class of medications known as anthelmintics. Ivermectin works by binding to and opening ion channels in the nerve and muscle cells of parasites, which leads to paralysis and death of the parasite.

Indications / Uses

The primary approved uses for ivermectin include the treatment of:

• Onchocerciasis (river blindness)
• Lymphatic filariasis
• Scabies
• Strongyloidiasis

While there has been discussion and research into off-label use, including for diseases like COVID-19, these uses remain controversial and largely unsupported by robust clinical evidence. Any such application should strictly occur under professional medical supervision.

Dosage Forms and Typical Dosing Considerations

Ivermectin is most commonly available in tablet form, although it can also be formulated as a topical cream. The dosage of ivermectin can vary based on the age, weight, and type of infection. For instance, the dose for treating onchocerciasis differs from that of treating scabies or lice. Specific dosing should be guided by a healthcare provider, as certain factors such as liver function and other medical conditions may require dose adjustment.

How to Take It Correctly Step-by-Step

1. Take ivermectin on an empty stomach with a full glass of water.
2. If you miss a dose, take it as soon as you remember unless it’s close to the time of your next dose.
3. Continue taking the full course as prescribed by your healthcare provider, even if symptoms improve earlier.
4. Store the medication at room temperature, away from moisture and heat.

Avoid common mistakes such as doubling doses, stopping the medication early, sharing it with others, or mixing it with alcohol.
