What It Is and How It Works
Ivermectin is an antiparasitic medication that is used to treat infections caused by certain parasites. It works by binding to parts of the parasite\’s nerve and muscle cells, leading to paralysis and death of the parasites. This mechanism makes it effective in clearing infections from the body.
On a more technical level, ivermectin acts on the γ-aminobutyric acid (GABA) and glutamate-gated chloride channels in invertebrate nerve and muscle cells, resulting in increased permeability of cell membranes to chloride ions, leading to their immobilization.
Indications / Uses
Ivermectin is primarily used for treating parasitic infections such as:
- Onchocerciasis (river blindness)
- Lymphatic filariasis
- Strongyloidiasis
- Scabies
The use of ivermectin for treating other conditions may exist but should be strictly under the guidance of a healthcare professional, as effectiveness and safety may vary.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in oral tablet form, with the 12 mg dosage being one standard strength. Dosing is individualized based on the type of infection being treated, patient weight, and health condition.
Factors like age, kidney and liver function, pregnancy, breastfeeding status, and concurrent use of other medications may influence dosing. Always follow the prescription instructions provided by your healthcare provider.
How to Take It Correctly Step-by-Step
- Take ivermectin orally with a full glass of water.
