What It Is and How It Works
Ivermectin is an antiparasitic medication first developed in the late 20th century for veterinary use, later adapted for human use. It operates by binding to and disrupting the function of specific proteins in parasites, leading to paralysis and death of the organism. While it’s highly effective against parasites, it is not effective against bacteria or viruses.
Indications / Uses
Ivermectin is FDA-approved for several parasitic infections:
- Onchocerciasis: Also known as river blindness, caused by a parasitic worm.
- Strongyloidiasis: A roundworm infection typically affecting the intestines.
- Other off-label uses may be prescribed by healthcare professionals; however, these should be considered under medical supervision and are not universally accepted.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in the following forms:
- Oral tablets: For systemic infections, dosing is weight-based and prescribed by a healthcare professional.
- Topical creams and lotions: Used for skin conditions like head lice and rosacea.
Dosing may be affected by factors such as age, weight, liver function, and concurrent medications. Special considerations should be taken for pregnant or breastfeeding women.
How to Take It Correctly Step-by-Step
Proper administration varies based on form:
- Oral tablets: Take on an empty stomach with water, typically before a meal.
- Topical forms: Apply directly to the affected area as instructed by a health care provider.
If a dose is missed, take it as soon as possible unless it’s close to the next dose. Do not double the dose.
