What It Is and How It Works
Ivermectin is an anti-parasitic medication used to treat a variety of parasitic infections. The drug works by binding to glutamate-gated chloride channels unique to invertebrates, resulting in paralysis and eventual death of the parasites. Its mechanism is specific to parasites, minimizing effects on human host cells.
Indications / Uses
Ivermectin is approved for use in treating conditions such as onchocerciasis (river blindness), strongyloidiasis, and other parasitic infections. In some cases, it is used in veterinary medicine. Off-label uses exist but should only be explored under strict supervision from a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablets, topical creams, and lotions. Dosing is case-dependent and altered based on factors like patient weight, existing health conditions, and potential interactions with other medications. It\’s important for patients to follow dosing instructions provided by their healthcare provider or the prescription label.
How to Take It Correctly Step-by-Step
When taking ivermectin orally, follow these general guidelines:
- Take the medication as prescribed, usually on an empty stomach with water.
- If a dose is missed, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose.
- Store ivermectin at room temperature, away from moisture and heat.
- Avoid alcohol, as it may exacerbate side effects.
- Never double doses to make up for a missed one.
