What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the avermectin family, used primarily to treat several types of parasitic infections. It works by binding selectively to glutamate-gated chloride ion channels, which are critical to the functioning of nerve and muscle cells in parasites. This binding results in heightened permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite.
Indications / Uses
The primary uses for ivermectin include the treatment of:
- Onchocerciasis (river blindness): This condition is caused by the worm Onchocerca volvulus and is prevalent in sub-Saharan Africa.
- Strongyloidiasis: An intestinal infection caused by the roundworm Strongyloides stercoralis.
While ivermectin has been discussed in various contexts, its off-label use should only occur under strict healthcare professional supervision, as rigorous evidence and guidelines are not universally established.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in tablet form for oral administration and as topical creams or lotions for other applications. Dosages can vary based on condition, weight, and individual health factors. It\’s crucial that patients follow the dosing instructions provided by their physicians or pharmacists, as deviations can result in reduced efficacy or increased risk of side effects. Factors like age, kidney function, and liver health may alter dosing requirements, making personalized medical guidance essential.
How to Take It Correctly
When taking ivermectin:
- Take orally on an empty stomach, at least 1 hour before meals.
