What It Is and How It Works
Ivermectin is an antiparasitic agent that works by interfering with the transmission of neural impulses in parasites, leading to their paralysis and death. It acts specifically on the neurotransmitter gamma-aminobutyric acid (GABA) and glutamate-gated chloride channels, which are present in parasites but not in mammalian tissues, making it effective and relatively safe in targeted animal applications.
Indications / Uses
In veterinary medicine, ivermectin paste is primarily approved for the treatment and prevention of parasitic infections in livestock such as horses and cattle. These include worms like strongyles and ascarids, mites, and lice. In humans, while ivermectin is approved in tablet form for conditions like onchocerciasis (river blindness) and strongyloidiasis, the use of paste versions for human medical conditions is not officially approved and should only be considered under medical supervision for specific, adequately justified cases.
Dosage Forms and Typical Dosing Considerations
Ivermectin paste is commonly available in strengths tailored for animal use, often measured in milligrams per gram of paste. Human dosages, when appropriate, should strictly adhere to the guidance of a healthcare provider, as inappropriate use can lead to overdose and toxicity. Factors affecting dosing include the specific parasite, the weight of the individual (or animal), and any coexisting health conditions.
How to Take It Correctly Step-by-Step
For animal treatment, ivermectin paste is administered orally. For human considerations, a healthcare provider should determine the appropriate dosage form and conditions under which ivermectin is safe and effective for off-label uses, if any. Key precautions include:
- Follow veterinary dosing instructions for animal treatment.
- Consult your doctor before considering any off-label use.
- Store paste in a cool, dry place away from children and pets.
