What It Is and How It Works
Ivermectin is an antiparasitic agent, commonly used to treat infections caused by various types of parasites. It works by binding to certain chloride channels in parasites, which leads to increased permeability of the membrane, causing paralysis and death of the parasites. Though primarily used for infestations such as lice and scabies, it is also used for certain nematode infections like strongyloidiasis and onchocerciasis. Its utility in treating other conditions is still under review and should be approached with professional guidance.
Indications / Uses
The primary approved uses for ivermectin include the treatment of parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis (roundworm infection)
- Scabies and lice (in specific formulations)
While there has been interest in ivermectin for off-label uses, especially during the pandemic, these applications should only be considered under the strict guidance of a healthcare provider, due to the lack of sufficient evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin comes in several forms, including oral tablets, topical creams, and injectables for animals. The appropriate form and dosage depend on the condition being treated, the patient\’s age, weight, and other medical factors. For oral formulations, it is generally recommended to take ivermectin on an empty stomach with water. Dosing may differ for people with hepatic or renal impairments, and professional advice is necessary to ensure safety and efficacy.
