- Scabies
- Head lice
- Some off-label uses include treatments for other types of parasitic infections and certain viral diseases under clinical investigation, but these should only be explored under clinician supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablets, creams, and topical lotions. The dosing depends on the type and severity of the infection and may vary based on individual factors such as weight, age, and kidney function.
