What It Is and How It Works
Ivermectin is an anthelmintic agent, meaning it\’s used to treat infections caused by parasitic worms. It works by binding to certain chloride channels, increasing the permeability of cell membranes in insects and worms, which leads to their paralysis and death. This mechanism disrupts the nerve and muscle function of these parasites, effectively eliminating them from the body.
Indications / Uses
Ivermectin is approved to treat several parasitic infections:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Head lice (off-label use)
- Scabies (off-label use)
Potential off-label uses should only be considered under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Oral ivermectin is available primarily in tablet form. Dosing considerations depend on the type of infection, patient weight, and individual health conditions. Special populations, such as pregnant women, elderly patients, or those with liver or kidney issues, require additional consideration for dosing decisions. Always follow the prescription label and guidance from a healthcare provider.
