Cautious use under professional supervision is advised when considering off-label applications, reflecting current clinical evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form, with topical formulations used for skin conditions. Dosage is determined by factors such as body weight, type of infection, and individual health status:
