What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to specific chloride channels in nerve and muscle cells of invertebrates, leading to paralysis and death of the parasite. In medical terms, it is known as a macrocyclic lactone, which targets nematodes (roundworms) and ectoparasites (mites and lice).

- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Lice and scabies (topical forms)
The medication has also been investigated for other uses, such as in the management of COVID-19, though these are off-label and highly debated within the scientific community. Always consult a healthcare professional before considering ivermectin for uses outside its approved indications.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral tablets (commonly at strengths of 3 mg, 6 mg, and 12 mg)
- Topical creams and lotions (for lice and scabies)
Typical dosing is influenced by body weight, the specific condition being treated, and patient factors such as liver function. It is critical to follow the specific dosing instructions provided by a healthcare professional.
How to Take It Correctly Step-by-Step
