What are the potential side effects associated with higher dosages of Ivermectin, such as those near 0.5 mg/kg or higher?

At higher dosages, side effects such as blurry vision and dizziness have been reported. Doc Frank’s experience notes that if blurry vision occurs, it is typically restored once the drug is discontinued. Higher doses (up to 2 mg/kg) may be administered less frequently (e.g., once weekly) to minimize side effects.
