What It Is and How It Works
Ivermectin belongs to a class of drugs called anti-parasitics. It works by binding to specific proteins in parasites, enhancing the release of inhibitory neurotransmission which results in paralysis and death of the parasite. This action reduces the ability of parasites to reproduce and spread, effectively treating infections such as strongyloidiasis and onchocerciasis. While the primary action is on parasites, certain off-label uses have been explored but should be considered cautiously and under medical supervision.
Indications / Uses
Ivermectin is approved primarily for treating two main types of parasitic infections:
- Strongyloidiasis: An infection caused by a type of roundworm.
- Onchocerciasis: Also known as river blindness, caused by a different type of parasitic worm.
Off-label uses include treatment for scabies and lice infestations, but these should only be pursued following a doctor\’s consultation due to varying evidence of efficacy and safety in different populations.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablets taken orally. It can also be found in topical formulations for conditions affecting the skin. Medication dosage depends on various factors, including the type of infection, patient age, weight, and overall health condition. For oral tablets, dosing is generally weight-based and administered as a single or series of doses. Always follow healthcare provider instructions and the specific prescription label.
How to Take It Correctly Step-by-Step
- Take oral ivermectin on an empty stomach, with water, ideally one hour before or two hours after meals, to maximize absorption.
- If a dose is missed, take it as soon as you remember unless it\’s almost time for the next dose. Do not double dose.
- Store at room temperature, away from moisture and heat.
- Avoid alcohol and follow specific dietary restrictions recommended by your healthcare provider.
