What It Is and How It Works
Ivermectin is an antiparasitic agent primarily acting by interfering with the nervous system of parasites. It binds to specific channels in the nerve cells of parasites, leading to paralysis and death. Importantly, it does not affect human nerve channels in the same way, which makes it useful in treating infections without causing harm to the human host.
Indications / Uses
In humans, ivermectin is primarily indicated for treating parasitic infections such as:
- River blindness (onchocerciasis)
- Lymphatic filariasis
- Intestinal strongyloidiasis
- Scabies
- Head lice
While there has been interest in using ivermectin for COVID-19, this use is not FDA-approved and should only be conducted in clinical trials or under expert guidance due to a lack of conclusive evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Tablets: Generally taken orally with water and on an empty stomach. Commonly used for systemic infections.
- Topical formulations: Used for skin conditions like scabies or head lice.
- Injectables: Primarily used in veterinary medicine and should not be used in humans unless explicitly prescribed by a healthcare provider.
Dosage can depend on the infection being treated, the patient\’s weight, age, and overall health. Specific guidance from a healthcare provider is crucial, especially in pediatric patients and individuals with liver or kidney complications.
How to Take It Correctly Step-by-Step
- Follow your healthcare provider\’s prescription carefully and use it exactly as directed.
- Take oral tablets on an empty stomach with a full glass of water.
