What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat several parasitic infections. It belongs to a class of drugs called anthelmintics. Ivermectin works by binding to certain chlorine channels in the nerve and muscle cells of parasites, leading to increased permeability of cell membranes to chloride ions. This causes paralysis and death of the parasites, effectively treating the infection.
Indications / Uses
The primary approved uses of ivermectin tablets include treating conditions such as onchocerciasis (river blindness), a parasitic disease caused by worms, and strongyloidiasis, a roundworm infection. Both conditions are typically found in tropical and subtropical regions. Ivermectin may also be used off-label for other parasitic infections, but such use should be under the guidance of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in tablet form for oral administration. Dosing can be influenced by factors such as the patient\’s age, weight, kidney and liver function, and severity of the infection. Patients should follow their healthcare provider\’s instructions closely and refer to the prescription label for accurate dosing.
