What It Is and How It Works
Ivermectin is an antiparasitic medication initially developed for veterinary use and later approved for human use. It targets parasitic worms by binding to ion channels in nerve and muscle cells, leading to paralysis and death of the parasites. This action is selective to parasites, making it effective against many parasitic infections while being relatively safe for humans.
Indications / Uses
Primarily, ivermectin is used to treat parasitic infections such as:
- Strongyloidiasis: An intestinal infection caused by a type of roundworm.
- Onchocerciasis: Also known as river blindness, it\’s caused by infection with the parasitic worm Onchocerca volvulus.
While there is interest in off-label uses, such practices should only be conducted under strict medical supervision and according to guidelines specific to each country.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in oral tablet form for human use. Dosage typically depends on the user\’s weight and the infection being treated. The standard dose may be a single oral dose of ivermectin with water on an empty stomach. Variations in dosing can occur depending on factors like age, body weight, liver function, and interaction with other medications. Always adhere to the prescribed dosage and instructions, as directed by a healthcare professional.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach with a full glass of water.
- Preferably take it at least one hour before or two hours after a meal.
- If a dose is missed, take it as soon as remembered unless it\’s near the time of the next dose.
- Store at room temperature, away from moisture and heat.
- Avoid alcohol as it may increase certain side effects.
Avoid sharing the medication with others and do not take it in larger amounts than prescribed by your healthcare provider.
