Ivermectin 12 mg
typically begins to work within a few hours to a couple of days after taking it, depending on the type of parasite being targeted and the condition being treated.
Here's a general breakdown:
For intestinal parasites (e.g., strongyloidiasis): You may start seeing results within 1–2 days, but complete clearance can take a few days to a week.
For scabies or lice: Improvement may begin within 24–48 hours, with itching or skin irritation often persisting for a few days as dead mites or lice and their waste are cleared by the body.
For onchocerciasis (river blindness): Ivermectin quickly kills microfilariae (larval stage), and you may notice symptom relief within a few days, though multiple treatments are often required over time for long-term control.
