What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to the chloride ion channels in the nerve and muscle cells of parasites. This binding increases the permeability of the cell membrane to chloride ions, causing paralysis and death of the parasite. This mechanism effectively clears parasitic infections from the body over time.
Indications / Uses
Primarily, ivermectin is used to treat certain parasitic infections in humans:
- Onchocerciasis: Commonly known as river blindness, this condition is caused by the parasite Onchocerca volvulus. Ivermectin is effective in reducing microfilariae levels in infected individuals, thereby alleviating symptoms and preventing progression.
- Strongyloidiasis: Caused by the parasitic worm Strongyloides stercoralis, this infection can lead to severe gastrointestinal issues. Ivermectin is an effective treatment by reducing the worm load.
There are off-label uses that garner attention, particularly related to viral infections, though these should only be considered with professional guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form. The typical dosing for strongyloidiasis involves a single oral dose based on body weight, while treatment for onchocerciasis may require periodic dosing. Factors such as liver or kidney function, presence of other medical conditions, and concurrent medication use can influence dosing decisions. Always adhere to the specific dosing guidance provided by a healthcare professional.
How to Take It Correctly Step-by-Step
Timing: Ivermectin should be taken on an empty stomach with water. Avoid food for at least 1 hour before and 2 hours after taking a dose.
- Follow the prescribed dosage schedule strictly and consult your physician if any adjustments are needed.
- Store ivermectin tablets in a cool, dry place, away from direct sunlight.
- If a dose is missed, take it as soon as remembered unless it is near the time for the next dose. Do not double doses.
- Avoid alcohol as it may exacerbate side effects.

Drug, Food, and Supplement Interactions
Ivermectin may interact with other medications, potentially altering its effectiveness or increasing side effect risks. Notable interactions include:
- Other CNS depressants: Such as alcohol, may enhance drowsiness.
