What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to a class of drugs known as avermectins. It works by binding to invertebrate nerve and muscle tissue chloride channels, causing increased permeability of the cell membrane leading to paralysis and death of the parasites. In simpler terms, it disrupts essential nervous system functions in parasites, effectively incapacitating them.
Indications / Uses
Ivermectin is approved for use in treating specific parasitic infections including:
- Onchocerciasis (river blindness): Eliminates larvae of the parasite Onchocerca volvulus present in the body.
- Strongyloidiasis: Used to treat infections caused by the roundworm Strongyloides stercoralis.
- Various off-label uses have been proposed, but such uses require careful supervision by a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin comes in various forms, with oral tablets being the most common for human use. Dosing depends on the specific medical condition being treated, patient weight, and other health parameters. Factors such as liver and kidney function, other ongoing medications, and potential comorbidities must be considered. Special care is needed in pediatric, elderly, and pregnant populations.
It is crucial not to self-prescribe and always follow the dosing instructions provided by a healthcare provider.
How to Take It Correctly Step-by-Step
Using ivermectin correctly ensures efficacy and reduces the risk of side effects:
- Take on an empty stomach with water unless otherwise advised by your doctor.

- If a dose is missed, take it as soon as you remember unless it is close to the time of your next dose. Do not double up on doses.
- Store at room temperature, away from moisture and heat.
- Adhere to the full prescribed course, even if symptoms improve before the course is completed.
