Treatment Protocols: Gastric decontamination methods such as activated charcoal Monitoring vital signs and organ functions in a hospital setting Intravenous fluids to prevent dehydration and support circulation Medications to counteract toxicity, such as antithyroid drug antidotes if available Treating symptoms such as nausea, fever, or bleeding In severe cases, procedures like plasmapheresis or dialysis might be necessary to remove toxins Close observation to prevent or manage complications
