What It Is and How It Works
Ivermectin is an antiparasitic agent. It binds to specific proteins, enhancing inhibitory neurotransmission in the parasites, leading to paralysis and eventual death. This disrupts the life cycle of the parasites, helping to clear infestations from the body. Ivermectin is not an antibiotic or antiviral, and its antiparasitic mechanism should not be confused with treating bacterial or viral infections.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections such as:
- Onchocerciasis (River blindness): Caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An intestinal infection caused by the parasite Strongyloides stercoralis.
- Scabies and lice infestations: Topical formulations are used for skin-based parasitic infections.
Off-label uses have included attempts to use ivermectin for viral conditions, although its effectiveness and safety for such uses remain subjects of clinical investigation and controversy. Consult a healthcare professional before considering ivermectin for any off-label purpose.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets, topical creams, and injectables:
- Tablets: Mainly used for human parasitic infections.
- Topical forms: Used for skin conditions like rosacea and lice.
Dosing depends on specific factors such as weight, the severity of infection, and the specific condition being treated. Individuals with liver impairment, pregnant or breastfeeding women, elderly adults, and children may require adjusted doses or different formulations. Always follow the specific dosing instructions provided by your doctor or pharmacist.
How to Take It Correctly Step-by-Step
When taking ivermectin orally, adhere to the following guidelines:
- Take ivermectin on an empty stomach, a couple of hours before or after meals.
- Consume with a full glass of water.
- If you miss a dose, take it as soon as you remember unless it is closer to your next dose. Do not double up doses.
- Store the medication at room temperature away from moisture and light.
Avoid alcohol, and do not share your medication with others, even if they have similar symptoms.
