Quick Facts
- Primarily used for treating parasitic infections, such as onchocerciasis and strongyloidiasis.
- Functions by paralyzing and killing parasites.
- Common forms include oral tablets and topical formulations.

What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to specific neurotransmitter receptors that are present in invertebrate species. This binding increases the permeability of cell membranes to chloride ions, resulting in paralysis and death of the parasite. Although this is the principal mechanism, the specific action may vary slightly depending on the organism it targets.
Indications / Uses
Ivermectin is primarily approved for certain parasitic infections:
- Onchocerciasis, also known as river blindness, commonly treated with ivermectin to eradicate the parasite, Onchocerca volvulus.
- Strongyloidiasis, an intestinal infection caused by the nematode Strongyloides stercoralis.
- Scabies and lice infections, where topical formulations are often preferred.
There is interest in potential off-label uses, but standard health authorities do not currently endorse these without specific clinical evidence and supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including:
- Oral tablets, typically ranging from 3mg to 18mg, depending on the condition treated.
- Topical creams or lotions often used for dermatological conditions such as rosacea.
Dosing is commonly based on body weight and specific infection treated. Kidney and liver function, as well as other medical conditions and concurrent medications, may influence dosing. Always consult a healthcare professional for dosing tailored to individual health needs.
How to Take It Correctly Step-by-Step
Following proper intake methods is crucial for effectiveness and safety:
- Take the oral tablet with a full glass of water on an empty stomach, about one hour before meals.
- If a dose is missed, take it as soon as remembered unless it is close to the time of the next dose; do not double doses.
- Store in a cool, dry place away from direct sunlight and out of reach of children.
- Avoid consuming alcohol, which can increase the likelihood of adverse effects.
