What It Is and How It Works
Ivermectin is a derivative of avermectin, a fermentation product of the soil bacterium Streptomyces avermitilis. It functions by binding to glutamate-gated chloride channels in nerve and muscle cells of parasites, causing paralysis and death. This action is specific to invertebrates, making it effective against a range of parasitic infections without affecting human cells.
Indications / Uses
Ivermectin is approved for treating several parasitic infections in humans, including onchocerciasis (river blindness), strongyloidiasis, and certain types of scabies and lice. Its use in veterinary medicine includes heartworm prevention in animals. While some have explored its use in treating COVID-19, these applications remain off-label and lack substantial clinical support.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including tablets, topical creams, and lotions. The dosing will depend on the specific condition being treated, the patient’s age, weight, liver function, and other factors. It is crucial to follow the prescription label or consult a healthcare provider for precise dosing instructions.
How to Take It Correctly Step-by-Step
Here are some general tips for taking ivermectin:
- Take on an empty stomach with water unless otherwise directed.
- If you miss a dose, take it as soon as you remember unless it’s close to the next scheduled dose.
- Do not double up on doses if you miss one.
- Store at room temperature away from moisture and heat.
