What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat infections caused by certain parasites. The drug works by binding to proteins in the parasites that disrupt nerve and muscle function, leading to paralysis and death of the parasites. This mechanism of action is effective in reducing parasite loads in the human body, alleviating symptoms, and preventing further transmission.
Indications / Uses
Ivermectin is approved for treating specific parasitic infections. In humans, it is most commonly used for:
- Strongyloidiasis: An intestinal infection caused by the nematode Strongyloides stercoralis.
- Onchocerciasis: Also known as river blindness, caused by the worm Onchocerca volvulus and transmitted through blackfly bites.
There are occasional discussions about off-label uses, but such uses should only be considered under professional medical supervision due to limited evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human medical use is commonly available in tablet form. Dosing may vary based on the specific parasitic infection being treated. Physicians determine the dose based on the patient\’s weight, the severity of the infection, and other health conditions. Special considerations in dosing are necessary for those with liver impairments, elderly individuals, pregnant women, and children. Always follow the prescription label and guidance from healthcare professionals.
