What It Is and How It Works
Ivermectin is an antiparasitic medication originally derived from the bacterium Streptomyces avermitilis. It functions by binding to the internal structures of worms and parasites, thereby causing paralysis and death of the parasite. This mechanism disrupts essential biological functions in parasites, leading to their elimination from the host body.
Indications / Uses
Primarily, ivermectin is approved for treating certain parasitic infections such as:
- Strongyloidiasis (intestinal infection caused by a type of roundworm)
- Onchocerciasis (river blindness)
While ivermectin has been explored as an option for other uses, such as potential treatment in viral infections like COVID-19, it is not officially approved for these purposes. These off-label uses lack sufficient evidence and should only be pursued under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form, typically administered orally. The dosing of ivermectin can be complex as it depends on various factors, including the specific condition being treated, the patient’s weight, and other underlying health conditions.
It is crucial that dosing is determined by a healthcare provider, who can assess factors such as liver and kidney function, and potential interactions with other medications.
How to Take It Correctly Step-by-Step
- Take the tablet as prescribed by your healthcare provider.
- Usually taken on an empty stomach, at least an hour before or two hours after a meal.
- Follow the exact dosing schedule given by your doctor.
- If a dose is missed, take it as soon as you remember unless it is near the time of the next dose. Do not double doses.
