What It Is and How It Works
Ivermectin is an antiparasitic agent that works by affecting the nerve and muscle functions of parasites, leading to their paralysis and death. Originally discovered as a veterinary medicine, its effectiveness in treating human parasitic infections such as onchocerciasis (river blindness) and lymphatic filariasis is well-documented.
Technical Detail: Ivermectin binds to glutamate-gated chloride ion channels, increasing permeability to chloride ions, which plays a critical role in disrupting neurotransmission in parasites.
Indications / Uses
Approved Uses: Ivermectin is commonly prescribed for treating onchocerciasis, lymphatic filariasis, strongyloidiasis, and other worm infections. It is also used to treat scabies and lice infestations.
Off-label Uses: Off-label use of ivermectin has been suggested for a variety of other conditions, but such uses should only be considered with strong evidence under professional medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablets, topical creams, and lotions. The dosing and form depend on the infection being treated. Factors like patient age, weight, liver function, and other medical conditions influence dosing. The medication is typically taken on an empty stomach with water.
General Dosing: Follow the prescription label and consult your healthcare provider for personalized dosing instructions. It is paramount to adhere strictly to your healthcare provider\’s guidance due to the potential variation in dosing requirements based on individual health profiles.
