What It Is and How It Works
Ivermectin is an antiparasitic agent effective against various internal and external parasites. It targets specific kinds of neurons in parasites, opening channels that lead to nerve and muscle paralysis. This ultimately leads to the parasites\’ death or incapacity to reproduce, thereby clearing the infection from the host\’s system.
Indications / Uses
Approved by health authorities for treating specific infections, ivermectin is primarily used for:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
It may also be used in a healthcare setting for other parasitic infections under certain conditions. Off-label uses should only be considered under medical supervision due to limited and mixed evidence on efficacy and safety.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in tablet form for human use. Doses are based on body weight, the type of infection, and specific patient needs such as existing liver or kidney issues which can affect metabolism. It\’s crucial to follow a healthcare professional\’s prescribed dosing schedule.
How to Take It Correctly Step-by-Step
- Take the medication with a full glass of water on an empty stomach, or as directed by your healthcare provider.
- It\’s important to adhere to the dosage and schedule prescribed, without doubling doses if one is missed.
- Store in a cool, dry place, away from excess heat and moisture.
- Avoid alcohol and other sedative substances while taking ivermectin.
