What It Is and How It Works
Ivermectin is an antiparasitic medication commonly used to treat infections caused by worms, lice, and other parasites. It belongs to a class of drugs called avermectins, which work by disrupting nerve and muscle function in parasites, ultimately leading to their death.
This disruption occurs when ivermectin binds to specific chloride channels that regulate neurotransmission. While this effect is toxic to parasites, it is relatively harmless to humans at prescribed doses, as these channels do not exist in humans or are located in parts of the nervous system that ivermectin cannot cross.
Indications / Uses
Ivermectin is approved for treating several types of parasitic infections. These include:
- Onchocerciasis (River Blindness): Caused by the parasitic worm Onchocerca volvulus.
- Lymphatic Filariasis: Affects the lymphatic system and is caused by filarial worms.
- Strongyloidiasis: An intestinal infection caused by Strongyloides stercoralis.
- Scabies and Head Lice: Topical ivermectin can be used to treat these infestations.
Off-label uses may exist but should be managed by a healthcare professional. Any use beyond approved indications should be approached with caution due to limited evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including oral tablets, creams, and lotions. The choice of formulation and dosage depends on the nature of the infection and patient-specific factors such as body weight, age, and organ function.
Typical dosing is often weight-based, particularly for oral formulations. For example, the dose for treating certain parasitic infections might be calculated based on the patient’s body weight in kilograms. Patients should closely follow their healthcare provider’s dosing instructions to ensure effectiveness and minimize side effects.
For those with liver or kidney disease, dosing adjustments may be necessary, underscoring the importance of professional guidance.
