In some cases, it is also used off-label to treat scabies or lice infestations. While there has been discussion about its use for treating viral infections, such applications are still under investigation and should only proceed under strict clinical guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including oral tablets and topical creams/lotions. The typical dosing depends on the condition being treated and the form of ivermectin used. Factors such as the patient\’s age, weight, kidney and liver function, and concurrent medications may impact the dosing decisions. Patients should follow the dosing regimen as prescribed by their healthcare provider and should not alter the dose without professional advice.

When prescribed in tablet form, ivermectin should generally be taken on an empty stomach with a full glass of water.
