What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to the glutamate-gated chloride channels in parasites, leading to increased permeability of the cell membrane to chloride ions. This results in paralysis and death of the parasite. It is effective against a range of parasites, including those causing river blindness (onchocerciasis) and lymphatic filariasis.
Indications / Uses
Ivermectin is primarily used to treat infections caused by certain parasites. It is commonly prescribed for:
- Onchocerciasis (river blindness)
- Strongyloidiasis (threadworm infection)
- Scabies (a skin infestation by mites)
- Pediculosis (lice infestation)
In some cases, ivermectin is also used off-label for other conditions, but such use should only occur under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including oral tablets and topical creams or lotions. The dosing of ivermectin depends on the condition being treated, the patient’s weight, and other health factors.
