What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitic agents. It works by binding to specific ion channels in the nerve and muscle cells of parasites, leading to increased permeability and paralysis of these cells. This mechanism effectively kills the parasites and helps eliminate infections. Ivermectin does not directly kill all types of infections but modifies the immune response to expel them from the body.
Indications / Uses
Approved uses of ivermectin include the treatment of onchocerciasis (river blindness) and intestinal strongyloidiasis in humans. It has also been used for treating ectoparasitic infections like scabies and lice. Recently, ivermectin has been investigated for its potential role in treating other conditions, but these uses remain controversial and should only be considered under professional medical guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly found in tablet form for human use, though topical formulations and injection options exist in veterinary medicine. Dosing typically depends on the infection being treated and the individual\’s weight and health status. For systemic infections, it\’s administered as a single dose but may require repeated doses depending on the severity. Always follow the prescription label and your clinician\’s or pharmacist\’s advice for dosing.
How to Take It Correctly Step-by-Step
1. Take ivermectin on an empty stomach, usually at least one hour before or two hours after a meal.
2. If you miss a dose, take it as soon as you remember unless it\’s almost time for the next dose. Do not double the dose.
3. Store ivermectin at room temperature, away from moisture and heat.
4. Avoid consuming alcohol while taking ivermectin as it might exacerbate side effects.
5. Do not share your medication with others, even if they have similar symptoms.
