Ivermectin is an effective medication for treating scabies, but its duration of action and effectiveness in killing scabies mites can vary depending on several factors. Typically, a single oral dose of ivermectin (200 micrograms per kilogram of body weight) is administered, and it takes around 2 weeks for the medication to start showing its effects. The mites begin to die off within 24 hours of treatment, but it may take longer for the symptoms to fully resolve. In some cases, a second dose may be necessary if the infestation persists, especially in cases of crusted scabies where the mites are more deeply embedded in the skin.
The duration of treatment with ivermectin for scabies is generally longer than that of topical treatments. A single dose of Ivermectin Pills may need to be repeated after 2 weeks if the infestation persists. In severe cases, such as crusted scabies, multiple doses may be necessary, with the second dose typically given 2 weeks after the first. It is essential to follow the prescribed treatment regimen and not stop using the medication prematurely, as this can lead to treatment failure and prolonged infestation. The overall effectiveness of ivermectin in treating scabies is generally high, with cure rates ranging from 40% to 90% in various studies.
