What It Is and How It Works

Ivermectin is an antiparasitic medication that works by binding to specific chloride channels in the nerve and muscle cells of parasites, causing paralysis and death. It effectively targets a wide range of parasites, disrupting their central nervous systems, which prevents them from reproducing and ultimately leads to their elimination from the host body. It\’s crucial to note that while ivermectin is highly effective for certain parasitic infections, its effectiveness for other conditions is subject to scientific validation.

Indications / Uses

Ivermectin is approved for treating several parasitic infections. These include:

• River Blindness (Onchocerciasis): Caused by the parasite Onchocerca volvulus.
• Strongyloidiasis: An infection caused by the intestinal worm Strongyloides stercoralis.
• Lice and Scabies: Topical formulations of ivermectin are used for these conditions.

Off-label, ivermectin has been explored for other uses, but such applications should only be considered under strict medical guidance.

Dosage Forms and Typical Dosing Considerations

Ivermectin is primarily available in the following forms:

• Oral Tablets: Typically prescribed for systemic infections.
• Topical Cream and Lotion: Used for skin infestations like lice and scabies.

Dosing varies based on the indication, patient age, weight, and kidney or liver functionality. It is critical to follow the prescription label and consult with your healthcare provider to ensure the correct dosage and administration.

How to Take It Correctly Step-by-Step

1. Take oral ivermectin on an empty stomach, about one hour before food.
