T40.901

Clinical Causes: Accidental ingestion of unidentified or mislabeled substances Contaminated or adulterated drugs purchased from unregulated sources Taking an unfamiliar drug without proper knowledge of its effects Unintentional exposure to psychoactive substances during recreational activities Misuse of over-the-counter or herbal products containing psychoactive compounds

Key Symptoms: Altered perception of reality, including visual or auditory hallucinations Confusion or disorientation Dilated pupils Changes in heart rate — either rapid or irregular Blood pressure fluctuations Nausea or vomiting Anxiety, restlessness, or paranoia Dizziness or loss of coordination Tremors or muscle weakness In extreme cases, psychosis or seizures

Diagnosis Path: Diagnosis is typically based on clinical history, observation of symptoms, and exclusion of other medical conditions. Since the poisoning involves an unspecified substance, laboratory testing might not identify a specific drug, but blood or urine tests can sometimes detect certain substances if available. Medical professionals will often consider the patient's recent exposure history and symptoms to determine the cause and the severity of the poisoning.

Treatment Protocols: Management of poisoning by unspecified hallucinogens involves supportive care aimed at stabilizing the patient. This may include monitoring vital signs, providing a calm environment to reduce agitation, and administering medications to control symptoms such as nausea or severe agitation. In some cases, activated charcoal might be used if ingestion was recent to limit absorption. Hospitalization could be necessary if symptoms are severe or if complications, such as seizures or psychosis, develop. Long-term treatment may involve psychological support or counseling if lasting mental health effects occur.
