What It Is and How It Works
Ivermectin is classified as an antiparasitic agent. It is used to eliminate or control a variety of parasitic infections by binding to specific sites on parasites\’ nerve and muscle systems, leading to paralysis and death of the parasite. For human parasitic infections, ivermectin disrupts the nervous system of the parasite, which ultimately stops the infection cycle.
Indications / Uses
The primary uses of ivermectin tablets in humans include the treatment of:
- Strongyloidiasis: A roundworm infection that affects the intestines.
- Onchocerciasis: Also known as river blindness, caused by a parasite found in certain regions of Africa and Latin America.
Off-label uses of ivermectin should only be considered under the supervision of a healthcare professional and are not universally sanctioned for other conditions beyond these primary indications.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly administered in tablet form. Dosing depends on the specific infection being treated, the patient\’s weight, and other medical considerations. Other conditions affecting dosing may include age, liver function, concomitant medications, and the presence of other medical conditions. It\’s crucial for patients to adhere to the prescribed dosing regimen and consult their healthcare provider with any questions or concerns about their medication.
How to Take It Correctly Step-by-Step
- Take ivermectin tablets with water on an empty stomach, at least one hour before or two hours after a meal.
- If a dose is missed, take it as soon as you remember, but skip the missed dose if it\’s almost time for your next scheduled dose.
- Do not double doses to make up for a missed dose.
- Store tablets at room temperature, protected from moisture and heat.
- Avoid consuming alcohol during treatment, as it can exacerbate side effects.
