Ivermectin's parasite-killing effects begin working quite quickly. Here's a short breakdown:

Rapid action: Ivermectin starts working on parasites within hours of administration.
Gradual elimination: It may take several days or even weeks to completely eliminate the entire parasite population depending on the type of parasite and the severity of the infection. ivermectin 3 mg tablets is one of the best solution

Noticeable improvement: You might experience some improvement in symptoms within a day or two, particularly itching or irritation caused by the parasites.
Important Note:

Even though Ivermectin acts fast, it's crucial to complete the full course of medication prescribed by your doctor to ensure complete elimination of the parasites and prevent them from coming back.

Mechanism of Action: Ivermectin disrupts the parasite's nervous system and neuromuscular function, essentially paralyzing them. This ultimately leads to their death.

Parasite Type Matters: The specific time it takes for ivermectin to work can vary depending on the type of parasite being treated. For instance, some studies suggest it might act faster against mites causing scabies compared to worms causing river blindness.
Dosage and Frequency: The prescribed dose and frequency of ivermectin can also influence how long it takes to see full results. In some cases, multiple doses might be necessary for complete eradication.

Individual Factors: Individual factors such as the severity of the infestation and your immune system's response can also play a role in how quickly you see improvement.
