What It Is and How It Works
Ivermectin is a medication belonging to the class of drugs known as antiparasitics. It works by binding to specific chloride ion channels in the nerve and muscle cells of parasites, leading to increased permeability of the cell membrane, paralysis, and death of the parasite. While primarily used against parasitic infections, questions about its potential antiviral effects have prompted research into broader applications.
Indications / Uses
Ivermectin is approved for use in treating infections caused by specific parasites, such as onchocerciasis (river blindness) and lymphatic filariasis. It is also commonly used for treating intestinal strongyloidiasis. Off-label, ivermectin has been studied for various conditions, though these uses require further clinical validation and should be undertaken only with a doctor’s guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form and topical formulations. Typical dosing is based on body weight and the type of infection being treated. For example, for intestinal strongyloidiasis, a single dose of oral ivermectin is given, while treating other conditions like lice may require a topical application. Dosage adjustments may be necessary for patients with liver or kidney impairments and require professional evaluation.
How to Take It Correctly Step-by-Step
It’s crucial to take ivermectin exactly as prescribed by a healthcare professional. For oral forms:
- Take ivermectin on an empty stomach with water.
- If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose.
- Do not double doses to catch up.
- Store at room temperature away from moisture and light.
Avoid common mistakes like sharing medication with others or combining it with alcohol without professional advice.
