Quick Facts
- Uses: Primarily used to treat parasitic infections such as onchocerciasis (river blindness) and lymphatic filariasis.
- Mechanism: Works by binding to the nervous system and muscle cells of parasites, causing paralysis and death.
- Forms: Available in tablets, topical creams, and injectable forms (veterinary use).

- Urgent Help: Seek immediate medical attention for signs of an allergic reaction or severe side effects.
What It Is and How It Works
Ivermectin is an antiparasitic medication that is effective against a variety of parasitic worms. It works by binding to glutamate-gated chloride channels found in the nerve and muscle cells of invertebrates, leading to increased permeability of the cell membrane to chloride ions, hyperpolarization, and eventual paralysis and death of the parasitic organism. This mechanism disrupts the nerve impulses of the parasites, effectively killing them.
Indications / Uses
Ivermectin is primarily used to treat parasitic infections in humans. Its approved uses include:
- Onchocerciasis: Also known as river blindness, caused by the parasitic worm Onchocerca volvulus.
- Lymphatic Filariasis: A disease caused by infection with the Filarioidea type of roundworms.
- Strongyloidiasis: An infection by the intestinal roundworm Strongyloides stercoralis.
While there has been interest in potential off-label uses, such as for treating certain viral infections, these uses are not supported by sufficient scientific evidence and should only be considered under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Tablets: Commonly used for treating parasitic infections in humans.
- Topical Creams: Used for treating conditions like rosacea.
- Injectable Forms: Primarily for veterinary use.
The dosing of ivermectin can vary based on the condition being treated, the patient’s weight, and other health factors. It is crucial to follow the prescribing information provided by a healthcare provider. Special considerations are necessary for patients with liver disease, children, and pregnant or breastfeeding women.
How to Take It Correctly Step-by-Step
When taking ivermectin, follow these general guidelines:
- With or Without Food: Typically taken on an empty stomach with water.
- Missed Dose: If you miss a dose, take it as soon as you remember, but skip it if it’s almost time for your next dose. Do not double up.
- Storage: Store at room temperature, away from moisture and heat.
