What It Is and How It Works
Ivermectin is an antiparasitic agent most commonly used to treat infections caused by roundworms, threadworms, and other parasites.

While there is ongoing research into potential off-label use cases, any such applications should only be undertaken under the guidance of a healthcare professional.
