What It Is and How It Works
Ivermectin is an antiparasitic medication that disrupts the nerve and muscle function of parasites, leading to their paralysis and eventual death. It is derived from a fermentation product of the bacterium Streptomyces avermitilis. This action is specific to the nervous systems of parasites and is generally safe for humans when used correctly.
Indications / Uses
The primary approved uses of ivermectin include the treatment of:
- Intestinal Strongyloidiasis: An infection caused by the parasite Strongyloides stercoralis, typically occurring in tropical and subtropical climates.
- Onchocerciasis (River Blindness): Caused by the parasitic worm Onchocerca volvulus, transmitted by blackfly bites.
It is also used off-label in some regions for treating other parasitic infections and is being studied for its potential in treating various conditions. However, off-label use should only be pursued under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations:
- Oral Tablets: Commonly used for systemic infections.
- Topical Creams and Lotions: Used for certain skin conditions.
Dosing depends on various factors, including the specific condition being treated, patient age, weight, kidney and liver function, and whether the patient is pregnant or breastfeeding. It\’s vital to adhere to professional medical guidance for dosing.
How to Take It Correctly Step-by-Step
- Take oral tablets with water on an empty stomach, usually before breakfast.
- Avoid taking with food, as this can increase absorption and lead to unwanted side effects.
- If using topical formulations, apply as directed to the affected area.
- Do not double doses if a previous dose is missed—contact a healthcare provider for advice.
- Store medication at room temperature, away from moisture and heat.
