What It Is and How It Works
Ivermectin is an antiparasitic medication known for its ability to treat infections caused by various parasites. It works by binding to the nerve and muscle cells of parasites, which causes paralysis and eventual death of the parasites. This mechanism is effective against parasites like those causing onchocerciasis (river blindness) and intestinal strongyloidiasis.
Indications / Uses
Ivermectin is primarily used to treat parasitic infections:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An infection caused by the Strongyloides stercoralis parasite, affecting the intestines.
It is also used off-label in certain cases under medical supervision, but this should be done based on clinical guidance due to potential risks and side effects.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in the following forms:
- Oral tablets
- Topical creams and lotions
The usual dose depends on the type and severity of the parasitic infection and the patient\’s overall health. Factors like liver function, age, weight, and other health conditions may influence the dosing regimen. It is crucial for patients to follow their healthcare provider\’s instructions and not adjust doses on their own.
How to Take It Correctly Step-by-Step
When taking ivermectin, follow these general steps:
- Take oral tablets with a full glass of water on an empty stomach, at least one hour before eating.
