Quick Facts About Ivermectin
- Ivermectin is used to treat certain parasitic infections in humans and animals.
- It functions by binding to and interfering with the nerve and muscle cells of parasites.
- Forms include tablets, creams, and topical solutions.
- It is often used to treat strongyloidiasis and river blindness in humans.
- Common side effects include nausea, dizziness, and diarrhea.
- Serious side effects can include confusion, low blood pressure, and seizures.

- Potential interactions with blood thinners and sedatives.
- Seek urgent help if severe allergic reactions or neurological symptoms occur.
What It Is and How It Works
Ivermectin is an antiparasitic agent. It works by binding to the glutamate-gated chloride channels in nerve and muscle cells, leading to paralysis and death of the parasite. This mechanism effectively targets certain parasitic worms causing conditions like strongyloidiasis and onchocerciasis (river blindness). Though some believe it has antiviral properties, most clinical guidelines do not support its use for viral infections like COVID-19 without further evidence.
Indications / Uses
Primarily, ivermectin is used in parasitic infections such as:
- Onchocerciasis (River Blindness): Caused by the worm Onchocerca volvulus.
- Strongyloidiasis: An intestinal disease caused by Strongyloides stercoralis.
- Lice and Scabies: Topical formulations can treat infestations.
Off-label uses have been suggested, but these should only be explored under professional supervision to avoid misuse and adverse effects.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral tablets, typically used for parasitic infections.
- Topical creams and lotions for skin infestations like lice and scabies.
Dosing is often calculated by body weight and the type of infection being treated. Factors influencing dosing include liver and kidney function, age, and presence of other medical conditions. It’s crucial to adhere to guidelines given by a healthcare professional.
How to Take It Correctly Step-by-Step
- Follow the prescription label for exact details on dosing.
- Take the medication with a glass of water on an empty stomach, unless directed otherwise.
- Do not double the dose if missed; simply take the next dose as scheduled.
- Store in a cool, dry place away from children and pets.
- Avoid self-medication and misuse by consulting a healthcare professional before starting or altering treatment.
