What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to specific proteins in parasites, leading to increased permeability of cellular membranes. This action causes paralysis and death of the parasite, effectively clearing the infection from the patient. Ivermectin affects a range of parasites, including those causing onchocerciasis (river blindness) and strongyloidiasis. It’s essential to understand that while ivermectin can eliminate parasites, it doesn\’t prevent them from recurring without proper preventive measures.
Indications / Uses
Ivermectin is officially approved for treating a variety of parasitic infections, such as:
- Onchocerciasis: Commonly known as river blindness, caused by worm parasites.
- Strongyloidiasis: Intestinal worm infections.
- Scabies: A skin condition caused by mites.
Although some proponents suggested ivermectin for COVID-19, its efficacy for this purpose is not supported by reliable, peer-reviewed studies and should only be observed within clinical trials or under strict professional consultation.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations:
- Tablets: Typically used for systemic infections like onchocerciasis and strongyloidiasis.
- Creams/Lotions: Primarily for topical conditions like scabies and head lice.
Dosing is contingent upon the specific condition being treated, patient\’s weight, age, liver function, and other health conditions. Dosing can be significantly different for children versus adults, underscoring the need for tailored medical prescriptions.
How to Take It Correctly Step-by-Step
For ivermectin tablets:
- Take on an empty stomach, with water unless otherwise directed.
- If a dose is missed, take it as soon as possible, but skip it if it\’s near the next scheduled dose.
