What It Is and How It Works
Ivermectin is an antiparasitic agent primarily used to treat infections caused by certain parasitic worms. It works by binding to specific chloride channels in nerve and muscle cells of the parasites, increasing cell membrane permeability and leading to paralysis and death. This action helps eliminate the parasites from the body, mitigating the infection.
Indications / Uses
Ivermectin is primarily indicated for the treatment of:
- Strongyloidiasis: A type of roundworm infection that affects the intestines.
- Onchocerciasis (river blindness): An infection caused by the worm Onchocerca volvulus.
While ivermectin has been studied for other uses, off-label use should only occur under the supervision of a healthcare provider due to the lack of definitive evidence and potential safety concerns.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form, with dosing based on body weight and specific condition being treated. It is important to follow the prescription label and the guidance of your healthcare provider, as factors such as liver function, other medications, and individual health conditions can influence dosing decisions.
