What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat infections caused by certain parasites. It functions by binding to the parasites’ nerve and muscle cells. This action increases the permeability of the cell membranes, often leading to paralysis and death of the parasite.
For more technically inclined medical audiences, ivermectin specifically targets the glutamate-gated chloride channels of parasites. This leads to an influx of chloride ions, resulting in hyperpolarization and paralysis of the parasite, which the body can then eliminate.
Indications / Uses
The primary approved uses for ivermectin in humans include the treatment of:
- Strongyloidiasis: An intestinal threadworm infection.
- Onchocerciasis: Also known as river blindness, caused by Onchocerca volvulus.
In some areas, ivermectin has also been used off-label under medical guidance for conditions like scabies and lice infestations. However, it\’s crucial to understand that any off-label use should be supervised by a healthcare professional due to varying evidence on effectiveness and safety.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in an oral tablet form, typically at 12 mg for maintaining standardized dosing. While self-treatment and modification are discouraged, dosing may depend on various factors including:
- Severity and type of parasitic infection.
- Body weight of the patient.
- Patient’s liver and kidney function.
- Combination with other medications.
Patients must follow the guidance of their healthcare provider and the prescription label instructions precisely. Healthcare professionals will determine the appropriate dosage and duration based on individual patient needs.
How to Take It Correctly Step-by-Step
- Timing: Take ivermectin on an empty stomach, one hour before breakfast or after, as food can influence absorption rates.
- Following Instructions: Swallow the tablet whole with a glass of water; do not split, chew, or crush.
- Missed Doses: If you miss a dose, take it as soon as you remember. If it\’s almost time for your next dose, skip the missed one. Do not double up on doses.
