What It Is and How It Works
Ivermectin is an antiparasitic agent used to treat several types of parasitic infections in humans. It works by binding to specific proteins and causing paralysis or death of the parasite. This inhibits their reproduction and alleviates the infection.
Indications / Uses
In humans, ivermectin is mainly used to treat conditions such as onchocerciasis (river blindness), strongyloidiasis, and other types of roundworm infections. It is also used for treating scabies and certain forms of lice. In some cases, off-label uses may include treatment for demodicosis and other uncommon parasitic infections; however, such uses should only be pursued under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form and as a topical cream or lotion. Dosage is primarily influenced by the type of infection, patient weight, and overall health. Special considerations are needed for dosing in pregnant or breastfeeding individuals, elderly patients, and those with liver or kidney impairment. Always follow healthcare provider instructions and the prescription label for dosing.
How to Take It Correctly Step-by-Step
Oral ivermectin should be taken on an empty stomach with a full glass of water. It is usually taken as a single dose or as directed by a healthcare provider. If a dose is missed, do not double up; instead, contact your healthcare provider for guidance. Store at room temperature away from moisture and heat.
