What It Is and How It Works
Ivermectin is an antiparasitic agent that targets a broad range of parasites. In humans, it\’s primarily prescribed for conditions such as onchocerciasis (river blindness) and strongyloidiasis. The drug works by binding to certain chloride channels in the parasites\’ nerve and muscle cells, increasing the permeability of the cell membrane to chloride ions. This leads to paralysis and death of the parasite.
Indications / Uses
Primarily, ivermectin is used to treat specific parasitic infections:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An infection by the roundworm Strongyloides stercoralis.
During the COVID-19 pandemic, there was interest in its potential off-label use for COVID-19 treatment, though such use remains controversial and is not universally supported by conclusive clinical data. Physicians considering off-label uses should rely on emerging evidence and clinical guidelines.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human use is most commonly available in tablet form, with dosing typically dependent on body weight and condition being treated. For instance, onchocerciasis treatment might involve a single dose that varies based on the patient\’s weight, repeated every six months if needed. Dosage can be affected by kidney or liver function and the presence of other medical conditions.
How to Take It Correctly Step-by-Step
- Take on an empty stomach: Typically, the drug is taken with water about an hour before breakfast.
- Do not split or crush tablets: Take the tablet whole to ensure proper dosing.
- Missed dose: If you miss a dose, take it as soon as you remember. If it is close to the time for your next dose, skip the missed dose and resume your regular schedule.
- Storage: Keep at room temperature away from moisture and heat.
