What It Is and How It Works

Ivermectin is an antiparasitic drug that is part of the avermectin family. It works by binding to specific channels in parasitic nerve and muscle cells, leading to paralysis and death of the parasites. In humans, it effectively treats infections such as onchocerciasis (river blindness) and strongyloidiasis.

Indications / Uses

The primary approved uses for ivermectin include treatment of certain parasitic infestations, like:

• Onchocerciasis (river blindness): Caused by the Onchocerca volvulus parasite.
• Strongyloidiasis: An infection caused by the Strongyloides stercoralis worm.

Off-label uses have been explored, particularly in the context of COVID-19, although these remain controversial and require more robust scientific evidence to be widely endorsed.

Dosage Forms and Typical Dosing Considerations

Ivermectin is typically available in the following forms:

• Oral tablets: Common for human use to treat parasitic infections.
• Topical formulations: Used for certain skin conditions like rosacea and lice.
• Injectable forms: Primarily used in veterinary medicine.

The dosage for ivermectin depends on the condition being treated, patient\’s weight, and medical history. Renal or hepatic impairment may require dosing adjustments, necessitating professional oversight.

How to Take It Correctly Step-by-Step

• Take ivermectin on an empty stomach with a full glass of water.
• If a dose is missed, take it as soon as remembered unless it’s almost time for the next dose; do not double doses.
