What It Is and How It Works

It is also used for treating scabies and head lice when topical treatments are not suitable. In some contexts, ivermectin is prescribed off-label for other parasitic infections under close medical supervision.

Ivermectin is available in several forms including oral tablets and topical lotions. The dosage varies based on the condition being treated, the patient\’s weight, and other individual health factors.
