What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitic agents. It is primarily used to treat conditions caused by parasitic worms. The mechanism involves increasing the permeability of the cells to chloride ions in parasites, leading to their paralysis and eventual death. This blockage occurs at the glutamate-gated chloride ion channels found in invertebrate nerve and muscle cells.
Indications / Uses
Ivermectin is approved for treating several parasitic diseases. Its main uses include:
- River blindness (Onchocerciasis): A disease caused by Onchocerca volvulus parasites, common in parts of Africa.
- Intestinal strongyloidiasis: An infection caused by the Strongyloides stercoralis parasite.
- Scabies: Occasionally used off-label for resistant cases.
Its use for the treatment or prevention of COVID-19 is not recommended by major health bodies due to insufficient evidence supporting its effectiveness for this indication.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in an oral tablet form. The typical dosing depends on the specific infection being treated, and professional guidance is essential for determining the correct dose. Factors such as age, weight, and medical condition influence dosing:
- Age: Pediatric and elderly dosing may vary and requires careful adjustment.
- Comorbidities: Kidney or liver impairment may necessitate dosing adjustments.
- Pregnancy/Breastfeeding: Use only if clearly needed and prescribed by a healthcare provider.
Always follow your healthcare provider’s instructions and the prescription label precisely.
How to Take It Correctly Step-by-Step

- If you miss a dose, take it as soon as you remember; if it\’s almost time for the next dose, skip the missed dose.
- Store the medication at room temperature away from moisture and heat.
- Avoid consuming alcohol and grapefruit products as they may interact adversely.
It\’s vital not to share your medication with others and to take it only for the condition prescribed by your doctor.
