Introduction
Ivermectin is a medication that has garnered attention for its use in treating various parasite infections in humans. It is a crucial drug for managing conditions such as onchocerciasis, known as river blindness, and intestinal strongyloidiasis. Despite being primarily utilized for these parasitic infections, ivermectin has been in the spotlight for its controversial potential use in other areas, often leading to misinformation about its purchase and usage. This article will provide an in-depth look at what ivermectin is, its uses, how it can be safely obtained, and essential considerations for its use in humans.

Quick Facts
- Ivermectin is primarily used to treat parasitic infections.
- It works by paralyzing and killing parasites.
- Common forms include tablets for oral intake.

What It Is and How It Works
Ivermectin is an antiparasitic agent. It functions by binding to the chloride channels in the nerve and muscle cells of parasites. This results in the paralysis and death of the parasites, effectively clearing the infection. This mechanism is particularly effective for specific nematodes and ectoparasites.
Indications / Uses
The primary approved uses of ivermectin include the treatment of river blindness (onchocerciasis) and strongyloidiasis, as well as other parasitic infections like scabies and head lice in some cases. While there has been research into off-label uses, such as for some viral infections, these uses are not universally supported or recommended without further conclusive evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form for oral administration. The dosing of ivermectin depends on the type of infection being treated, body weight, and other patient-specific factors such as kidney or liver function. It\’s crucial to follow the prescribed dosing information provided by a healthcare professional, as incorrect usage can lead to suboptimal effects or increased risk of side effects.
How to Take It Correctly Step-by-Step
When taking ivermectin, it should generally be consumed on an empty stomach, at least one hour before or two hours after a meal. Maintain the prescribed schedule and do not take double doses to make up for a missed one. Store ivermectin at room temperature and keep it out of reach of children. Avoid taking it alongside alcohol, as it may increase certain side effects or reduce efficacy.
