What It Is and How It Works
Ivermectin is an antiparasitic medication that affects nerve and muscle function in parasites, effectively paralyzing and killing them. It binds selectively to glutamate-gated chloride ion channels, which are vital for the survival of many parasites but are absent in humans. This specificity makes it a powerful tool against a range of parasitic infections.
Indications / Uses
Ivermectin was initially approved for treating parasitic infections such as onchocerciasis (river blindness) and lymphatic filariasis. It is also effective against scabies and head lice. Although discussed for other diseases, the FDA\’s approval is limited to these indications. Off-label use should only occur under healthcare supervision and with caution.
Dosage Forms and Typical Dosing Considerations
Available in oral tablets and topical formulations, dosing of ivermectin depends on the condition being treated, its severity, and patient-specific factors like age and weight. Healthcare professionals will consider liver function, other ongoing treatments, and overall health when prescribing ivermectin, emphasizing the importance of following professional guidance.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach with water unless instructed otherwise.
- If a dose is missed, take it as soon as remembered unless it\’s close to the next scheduled dose, then skip the missed dose—do not double doses.
- Store the medication at room temperature, away from excess heat and moisture.
- Avoid alcohol, as it may enhance the drowsiness side effect.
- Always complete the full treatment course as prescribed.
