What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to invertebrate nerve and muscle cells, causing paralysis and death of the parasite. Its effectiveness against a variety of parasites is due to its ability to target these specific cells, which are not present in humans or animals at similar sites, thus ensuring minimal systemic effects.
Indications / Uses
Ivermectin is approved primarily for the treatment of certain parasitic infections such as onchocerciasis (river blindness), intestinal strongyloidiasis, and lymphatic filariasis. It is also used off-label for external parasitic infestations, such as scabies and head lice. Off-label uses should only be pursued under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form for humans. The dosage depends on the specific condition being treated, the patient\’s weight, and overall health status. For example, dosage may differ for children, elderly, or those with liver impairments. It is crucial to follow the prescription label and the guidance of healthcare professionals.

- Avoid missing doses, but do not double the dose if missed. Continue with your regular schedule instead.
