What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to specific channels in the nerve and muscle cells of parasites. This action results in paralysis and eventual death of the parasites. In technical terms, ivermectin increases the permeability of cell membranes to chloride ions, leading to the disruption of neurotransmission in the parasites.
Indications / Uses
Primarily, ivermectin is approved for the treatment of various parasitic infections including onchocerciasis (river blindness), strongyloidiasis, and scabies. It is also used off-label for conditions such as head lice. Off-label use should always occur under the guidance of a healthcare professional, and benefits should be carefully weighed against potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in different dosage forms, such as oral tablets and topical formulations. Dosing depends on the infection being treated, patient weight, and other health considerations like liver and kidney function. Pregnant and breastfeeding women, as well as pediatric and geriatric patients, may require specific dosing adjustments. Always follow the prescribed regimen and consult a healthcare provider before any changes.
How to Take It Correctly Step-by-Step
For oral tablets, ivermectin is typically taken on an empty stomach with water. A missed dose should be taken as soon as remembered unless it is close to the time of the next dose. Do not double doses. Store medications at room temperature, away from excess heat and moisture. Avoid sharing medication and consult a healthcare provider about alcohol use while on ivermectin.
