What It Is and How It Works
Ivermectin is an anti-parasitic agent that functions by binding to components in the parasite\'s neural system. This binding causes an increase in the permeability of cell membranes to chloride ions, leading to paralysis and death of the parasites. It is especially effective against nematodes and arthropods.
While its primary function is to target parasites, it is sometimes investigated for other potential effects, but such uses should only occur under the direction of a healthcare professional.
Indications / Uses
Ivermectin is primarily prescribed for the treatment of:
- Strongyloidiasis: An intestinal infection caused by a type of roundworm.
- Onchocerciasis: Also known as river blindness, it is caused by the parasitic worm Onchocerca volvulus.
Off-label uses may exist but are not universally recommended and require medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available as oral tablets for humans. Dosing depends on the type and severity of the infection, weight of the patient, and other health considerations. Factors like age, liver function, and concurrent health conditions significantly influence dosing decisions, and these variations emphasize the importance of following personalized medical advice.
