What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the class of drugs known as avermectins. It works by binding to certain proteins (chloride channels) in the nervous system of parasites, which leads to paralysis and death of the parasite.
While ivermectin offers symptomatic relief by killing the parasites causing the disease, it does not cure the damage already done by parasites, particularly in chronic conditions like onchocerciasis.
Indications / Uses
Primarily, ivermectin is used to treat infections caused by certain parasitic worms. These include:
- Onchocerciasis: Often referred to as river blindness, this is prevalent in parts of Africa and is caused by the Onchocerca volvulus worm.
- Strongyloidiasis: This is a roundworm infection affecting the stomach and intestines, more common in tropical regions.
Off-label, ivermectin has been used in contexts such as scabies and lice treatment, but these uses should only occur under a healthcare professional’s guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human use is most commonly available as oral tablets. The dosing depends on the condition being treated, its severity, and patient factors. Generally, the dosage is calculated based on the patient’s body weight.
Healthcare providers consider factors like age, kidney function, liver function, and concurrent medications when determining the appropriate dosage. It\’s crucial for patients to follow their prescribing doctor\’s instructions carefully.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach with a full glass of water, usually one hour before a meal or two hours after.
- Follow the dosage schedule prescribed by your healthcare provider. Do not adjust the dose on your own.
- If you miss a dose, take it as soon as possible, unless it is almost time for your next dose.
- Store the medication at room temperature, away from excess heat and moisture.
- Avoid doubling doses if you miss one; follow healthcare provider\’s guidance for your next steps.
- Do not share your medication, as it is tailored for your specific infection and health condition.
