Treatment for dimenhydrinate toxicity focuses on supportive care and symptomatic management. Activated charcoal may be administered if the patient presents shortly after ingestion to limit drug absorption. Intravenous fluids are used to maintain hydration and correct electrolyte imbalances. In cases of severe toxicity, medications such as benzodiazepines may be used to control seizures, and mechanical ventilation may be required for respiratory support. Continuous monitoring of vital signs and cardiac function is essential.
