What It Is and How It Works
Ivermectin belongs to a class of medications known as antiparasitic agents.

It is also used off-label for conditions like head lice and rosacea. The use of ivermectin for non-FDA-approved conditions should strictly adhere to a healthcare professional\’s advice.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various formulations, including tablets, creams, and lotions. The typical oral dosing for parasitic infections is based on body weight and requires healthcare provider guidance to ensure efficacy and safety.
