Quick Facts
- Primarily used to treat parasitic infections such as river blindness and intestinal strongyloidiasis.
- Works by paralyzing and killing parasites.
- Commonly available as oral tablets.
- Typically, a single dose is taken with water on an empty stomach.
- Common side effects include nausea, diarrhea, dizziness, and itching.
- Inform your doctor of any liver or kidney disease.
- Avoid using in infants less than 15 kg or during breastfeeding without professional guidance.

What It Is and How It Works
Ivermectin is a broad-spectrum antiparasitic medication effective against various parasitic infections. It works by binding to certain chloride ion channels in the parasites, leading to increased permeability of the cell membrane. This disrupts the parasite\’s nerve and muscle function, ultimately resulting in paralysis and death. By affecting these specific channels, ivermectin is selective in its action, typically sparing host cells.
Indications / Uses
Ivermectin is predominantly used to treat:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Scabies (especially in severe or resistant cases)
- Lice infestations
In certain scenarios, ivermectin has been used off-label for other conditions such as certain types of rosacea or research into its antiviral potential; however, these uses should only be considered under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form, though topical formulations exist for specified conditions like head lice. The oral dose is usually calculated based on body weight, with a typical adult dose being around 150-200 micrograms per kilogram.
Dosing should be determined by a healthcare provider, taking into account factors such as:
- Age and weight
- Liver and kidney function
- Other underlying health conditions
- Current medications
It is crucial to adhere to prescribed doses to minimize the risk of adverse effects.
How to Take It Correctly Step-by-Step
Follow these steps for optimal use:
- Take ivermectin on an empty stomach, approximately one hour before food, with a full glass of water.
- If a dose is missed, take it as soon as you remember unless it is closer to the next scheduled dose. Do not double doses.
- Store at room temperature, away from moisture and heat.
- Avoid alcohol as it may exacerbate side effects.
Common mistakes include not completing the course or adjusting the dose without consulting a healthcare professional.
