What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. It inhibits the ability of parasites to produce energy, leading to paralysis and eventual death. This action disrupts the parasitic lifecycle, effectively treating infections caused by heartworm in animals and conditions such as strongyloidiasis and onchocerciasis in humans.
Indications / Uses
Ivermectin for human use has been approved for treating specific parasites. Conditions approved by health regulatory bodies include:
- Strongyloidiasis: An intestinal infection caused by Strongyloides stercoralis.
- Onchocerciasis: Also known as river blindness caused by Onchocerca volvulus.
- Scabies: A mite infestation causing itching and rash.
While there\’s been discussion around off-label uses, such as for COVID-19, these are not currently endorsed by health authorities without ongoing research and evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human use is typically available in oral tablet form. Dosage varies based on the specific infection being treated, weight, age, and overall health of the individual. It\’s crucial to follow the prescribed dosage by a healthcare provider.
Veterinarian formulations of ivermectin, found in retail outlets like Tractor Supply, are available as pour-on solutions, injectables, and oral pastes. These are formulated specifically for animal physiology and dosing and must not be substituted for human products.
How to Take It Correctly Step-by-Step
For those prescribed ivermectin, the following guidelines typically apply:
- Take ivermectin as prescribed by a healthcare provider.
- Administer on an empty stomach with water for optimal absorption.
- Avoid missing doses. In case of a missed dose, take it as soon as remembered unless it is close to the next scheduled dose.
- Store at room temperature, away from moisture and heat.
- Avoid alcohol while taking this medication.
- Do not share medication with others, even if they present similar symptoms.
