What It Is and How It Works
Ivermectin is an antiparasitic agent. It is commonly used to treat infections caused by parasites such as worms and mites. The drug works by binding to specific proteins in parasites’ nerve and muscle cells, which eventually leads to paralysis and death of the parasites. This mechanism effectively stops the spread of infection within the host.
Indications / Uses
Ivermectin is primarily approved for treating various parasitic infections. Some of the key approved uses include:
- Onchocerciasis (River Blindness): Caused by the filarial worm Onchocerca volvulus.
- Strongyloidiasis: An infection by the roundworm Strongyloides stercoralis.
- Scabies: A skin infestation caused by the mite Sarcoptes scabiei.
Ivermectin is sometimes prescribed off-label for other parasitic infections; however, these uses should only be pursued under medical supervision due to varying evidence supporting such applications.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various dosage forms, primarily oral tablets for systemic infections and topical formulations for specific conditions such as head lice and rosacea. The dosage depends on the infection type, patient weight, age, and overall health. It is crucial to follow the healthcare provider\'s prescription label and guidance.
Factors that affect dosing include:
- Patient\'s age and weight: Typically, the dose is calculated based on weight.
- Kidney and liver function: Dosing may need adjustment in cases of impaired function.
- Pregnancy and breastfeeding: Not typically recommended unless necessary.
How to Take It Correctly Step-by-Step
Proper adherence to prescribed dosing and administration is vital:
- Take oral ivermectin tablets on an empty stomach with water.
- Avoid food at least two hours before and after taking a dose.
- If you miss a dose, take it as soon as remembered unless it is close to the next dose. Do not double doses.
- Store tablets at room temperature, away from excess heat and moisture.
Avoid common mistakes such as altering the dose without consulting your doctor, using old prescriptions for new infections, or sharing your medication with others.
