What It Is and How It Works
Ivermectin is a medication used primarily to treat a variety of parasitic infections. It works by binding to invertebrate muscle and nerve cells, causing paralysis and death of the parasites. This action effectively clears the infection from the patient’s body. In more technical terms, ivermectin potentiates glutamate-gated chloride channels in invertebrate nerve and muscle cells, disrupting their normal function.
Indications / Uses
Ivermectin is prescribed for the treatment of several parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Scabies
- Helminth infections
Off-label use is not uncommon, but it should only be undertaken under medical supervision. Any additional indications, such as viral infections, are under investigation and are not currently standard practice.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets, topical creams for skin conditions, and injectable forms for veterinary use. The form and dosage depend on the infection being treated, the patient’s age, weight, and kidney or liver function.
Special populations might require dosing adjustments to reduce the risk of side effects or toxicity:
- Elderly Patients: May require lower doses.
- Patients with liver/kidney disease: Dosage may need adjustment based on organ function.
- Pediatric Patients: Dosing usually determined by the child\’s weight.
How to Take It Correctly Step-by-Step
