What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to the invertebrate nerve and muscle cells of parasites, causing paralysis and death of the parasite. Its primary mechanism involves enhancing the inhibitory effects of neurotransmitter gamma-aminobutyric acid (GABA) or opening glutamate-gated chloride channels, resulting in an increase in cellular permeability and the elimination of the parasite.
Indications / Uses
In humans, ivermectin is approved for the treatment of several types of parasitic infections, such as:
- Intestinal strongyloidiasis
- Onchocerciasis (river blindness)
- Other specific worm infections like scabies and lice under certain conditions
Its use for conditions like COVID-19 is controversial and should only be considered under clinical trials or professional guidance due to mixed evidence regarding its effectiveness.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablets and topical formulations. The general dosing is weight-based and varies depending on the condition being treated. Patients must follow the precise instructions provided by their healthcare provider. Factors influencing dosing include weight, age, potential liver or kidney function impairments, and concurrent medications. Pregnant or breastfeeding women should consult their healthcare providers for safe use.
How to Take it Correctly Step-by-Step
