Quick Facts
- Ivermectin is primarily used to treat parasitic infections.
- It works by paralyzing and killing parasites.
- Available in oral and topical forms.
- Common side effects include gastrointestinal disturbances and dizziness.

What It Is and How It Works
Ivermectin is an antiparasitic agent used to treat a variety of infections caused by worms, certain insects, and other parasites. It works by binding to parts of the parasites\’ cells, leading to paralysis and death. This blocks their ability to reproduce and eventually leads to the elimination of the infection. Although primarily used for parasitic infections, its mechanism of action has spurred research into potential off-label uses.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Head lice
- Scabies
Off-label uses have been explored but should only be pursued under the guidance of a healthcare professional due to varying evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablets and topical formulations. The dosing varies depending on the condition being treated, the patient\’s weight, and their medical history. For example, dosages for parasitic infections are often based on body weight. Patients with liver or kidney disease, pregnant or breastfeeding women, and elderly individuals may require dose adjustments.
How to Take It Correctly Step-by-Step
To use ivermectin safely and effectively, follow these general steps:
- Take ivermectin on an empty stomach with water unless otherwise advised by a healthcare provider.
- Adhere strictly to the prescribed dosing schedule.
- Store the medication as recommended, usually in a cool, dry place.
- If a dose is missed, take it as soon as you remember unless it\’s almost time for the next dose. Do not double up doses.
- Avoid alcohol as it may increase certain side effects.

| Option | Typical Use | Key Pros/Cons | Cautions |
|---|---|---|---|
| Ivermectin | Parasitic infections | Effective with a single dose but may cause dizziness | Use caution in liver disease |
| Albendazole | Variety of worm infections | Broad-spectrum but may require multiple doses | Monitor liver function |
