What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat certain types of parasitic infections in humans. Its mechanism of action involves binding to the glutamate-gated chloride ion channels in nerve and muscle cells of parasites, leading to paralysis and death of the parasite. This action effectively halts the infection progression and helps eliminate the parasites from the human host.
Indications / Uses
Ivermectin is FDA-approved primarily for treating certain parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal roundworm infections)
It has also been used off-label for the treatment of scabies and lice under specific medical guidance, although this should only be pursued under the supervision of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
For human use, ivermectin is commonly available in tablet form. The dosage is often determined based on weight, the type of infection, and the specific patient needs. Due to varying factors such as age, liver and kidney function, other health conditions, and concurrent medication, dosing must be tailored to each individual, following healthcare provider instructions and prescription labels.
How to Take It Correctly Step-by-Step
Taking ivermectin correctly includes:
- Taking it on an empty stomach with water unless directed otherwise by a healthcare professional.
- If a dose is missed, take it as soon as you remember unless it\'s near the time for your next dose. Do not double the dose to catch up.
- Storing the medication as directed, typically at room temperature, away from moisture and heat.
Side Effects Common to Serious
