Quick Facts
- Used primarily to treat infections caused by certain parasites.

- Rapid onset for treating parasitic infections, often noticeable within a few days.
- Common side effects: dizziness, nausea, mild skin rash.
- Should not be used without prescription; off-label uses have not been proven effective for other conditions.
- People with liver conditions should use caution and consult health professionals.
- Seek urgent help if experiencing symptoms of a severe allergic reaction, such as swelling or difficulty breathing.
What It Is and How It Works
Ivermectin is a broad-spectrum antiparasitic agent. It primarily works by interfering with the nervous and muscle functions of parasites. It binds to certain ion channels within parasites, which are critical to their nerve and muscle function. This binding results in paralysis and eventually death of the parasite. In technical terms, it increases chloride ion permeability affecting the parasite\'s ability to survive.
Indications / Uses
Ivermectin is primarily approved for treating:
- Intestinal strongyloidiasis, caused by the parasitic worm Strongyloides stercoralis.
- Onchocerciasis, or river blindness, caused by Onchocerca volvulus.
- Scabies and other skin infestations, particularly when other treatments have failed.
- Head lice in particular circumstances.
Off-label, ivermectin has been discussed for potential use in treating other conditions, though these uses should only be considered under professional supervision and are often not recommended by health authorities.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in the following forms:
- Oral tablets: Often used for parasitic infections.
- Topical creams and lotions: Used for skin conditions like scabies.
The dosing of ivermectin depends on various factors including age, weight, and specific condition. Proper dosage must always be directed by a healthcare provider, with special attention in cases involving pediatric patients, elderly adults, and those with liver or kidney impairments.
How to Take It Correctly Step-by-Step
- Take the oral form with water on an empty stomach, one hour before breakfast.
