T43.593

Clinical Causes: Intentional overdose or overdose attempts Misuse or abuse of antipsychotic medications Accidental ingestion, especially in children or vulnerable populations Deliberate poisoning in assault cases Erroneous medication administration or dosing errors Interaction with other drugs or substances leading to toxic levels

Key Symptoms: Drowsiness or excessive sleepiness Dizziness or feeling faint Confusion or disorientation Blurred vision Muscle stiffness or tremors Unusual movements or restlessness Slow or irregular heartbeat Low blood pressure Seizures in severe cases Respiratory depression Loss of consciousness

Diagnosis Path: Diagnosis involves a detailed medical history, including recent medication use and possible exposure scenarios, and a physical examination. Blood tests can detect elevated levels of antipsychotics or neuroleptics to confirm poisoning. Additional investigations such as electrocardiograms (ECG) may be performed to assess heart function, while laboratory tests can help evaluate organ function and detect complications. Healthcare providers also consider other causes for symptoms to differentiate poisoning from other medical conditions.

Treatment Protocols: Treatment for poisoning by antipsychotics and neuroleptics focuses on stabilizing the patient and preventing further absorption of the toxic substances. Immediate steps may include activated charcoal administration to absorb remaining medication in the gastrointestinal tract. Supportive care, such as intravenous fluids, oxygen therapy, and monitoring vital signs, is critical. In cases of severe toxicity, specific interventions like medications to reverse symptoms (antagonists), control seizures, or support cardiac function may be necessary. Continuous monitoring and hospitalization are often required to manage complications and promote recovery. Psychological or psychiatric evaluation might also be recommended after medical stabilization, especially if poisoning was intentional.
