What It Is and How It Works
Ivermectin is an anti-parasitic medication used globally to treat infections caused by certain parasitic worms. It works by binding to chloride ion channels in the nerve and muscle cells of parasites, causing paralysis and death of the parasites. This unique mode of action makes it effective against specific types of worms and ectoparasites like head lice and scabies.
Indications / Uses
Ivermectin is primarily approved for treating diseases like strongyloidiasis—a roundworm infection—and onchocerciasis, known as river blindness. It is also used for scabies and lice in topical formulations. Off-label, ivermectin has been explored for other viral diseases, though such uses should only be under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available as oral tablets, topical creams, and lotions. The typical oral dosage for parasitic infections varies based on the specific disease and patient\’s weight. It is crucial to follow prescribing healthcare professional guidelines, particularly concerning liver or kidney impairment, pregnancy, and concurrent medications, as these can influence dosing decisions.
How to Take It Correctly Step-by-Step
For oral ivermectin, take it on an empty stomach with water, ideally 1-2 hours before a meal for best absorption. If a dose is missed, take it as soon as remembered, unless it’s near the time of the next dose. Avoid doubling up doses. Store ivermectin at room temperature, away from excess heat and moisture.
