What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the class of drugs known as antiparasitics. It works by binding to proteins within the parasites, causing paralysis and death. For humans, these actions help eliminate parasitic worms such as those causing river blindness or strongyloidiasis, by disrupting the flow of ions crucial for nerve and muscle function in the parasites.

For human use, ivermectin is officially approved for the treatment of:
- Onchocerciasis (river blindness)
- Lymphatic filariasis
- Strongyloidiasis
- Head lice and rosacea (topical form)
Off-label uses may include scabies, though such treatments should only be conducted under a clinician\’s supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various formulations, including:
- Oral tablets for systemic infections
- Topical creams or lotions for skin conditions like rosacea or head lice
Dosing depends on the parasitic infection being treated. Factors such as age, weight, kidney function, liver status, and any coexisting medical conditions also play crucial roles in determining the appropriate dosage. Always follow the prescription label and guidance from a healthcare provider.
