Ivermectin is an effective antiparasitic medication used to treat various infections in humans, including scabies, strongyloidiasis, and river blindness (onchocerciasis). The time it takes for ivermectin to kill parasites depends on the type of infection, the severity of the infestation, and individual response to the medication.
After taking Ivermectin, it typically begins working within 24 to 48 hours, paralyzing and killing parasites. For scabies, the mites start dying within a day or two, but symptoms such as itching and skin irritation may take up to two weeks to fully resolve as the body clears dead parasites. In head lice infections, Ivermectin 12mg for Parasites works quickly, killing lice within 24 hours, though a second dose may be needed after 7 to 10 days to eliminate any remaining eggs.
For intestinal parasites like strongyloidiasis, Ivermectin may clear the infection within a few days, but in severe cases, additional doses may be required. In river blindness, the medication effectively reduces microfilariae (immature parasites) within 2 to 3 days, though complete symptom relief can take months.
The effectiveness of Ivermectin also depends on factors like dosage, immune system strength, and the severity of the infection. Some conditions may require repeated doses to fully eliminate parasites. While Ivermectin is generally well-tolerated, side effects such as nausea, dizziness, or mild skin reactions may occur.
Patients should always follow medical guidance and complete the prescribed treatment to ensure full parasite eradication. If symptoms persist beyond the expected time frame, a healthcare professional should be consulted for further evaluation.
