dextromethorphan and Poisoning

The incidence of serious pediatric morbidity and mortality has fortunately declined over the past two decades due to better prevention efforts, the development of regionalized poison information programs, and advances in the emergency management and critical care of poisoned patients. Still, children continue to explore and often ingest many substances they discover in their world. Some of these children will become patients who present to the emergency department, requiring a coordinated approach to the seriously or even critically ill poisoned child by physicians who can access specialized resources to manage a vast spectrum of potential toxins. This article summarized one such approach, emphasizing initial attention to life support priorities, followed by a detailed evaluation process using readily available clinical and laboratory data. Management strategies including decontamination, urgent antidotal therapy, initiation of excretion enhancement, and optimal supportive care were reviewed. Several specific intoxications were illustrated briefly in an attempt to facilitate pattern recognition of characteristic pediatric exposures.

Dextromethorphan, a common ingredient in cough syrups, has rarely been described to cause toxicity. The authors describe an unusual case of a known asthmatic presenting with somnolence, who appeared to be in end-stage respiratory failure. Her partial response to routine naloxone, 1 mg, was surprising. However, additional naloxone was required to completely normalize the patient's mental status. The authors suggest naloxone be administered in doses of 0.4 mg or more intravenously in suspected dextromethorphan overdose.

Drug poisoning is a frequent cause of hospitalization in children and youth. The aim of the study was to evaluate the prevalence of drug poisoning in children in the region of Rzeszów city.. Medical records of paediatric patients hospitalized in The Regional Hospital No. 2 in Rzeszow between 2010 and 2014 was reviewed and data were collected using scientific protocol. The following factors were analyzed: type of medication causing intoxication, the causality of the event, duration and seasonality of hospitalization as well as demographic data, such as the patient's age and sex.. Within the analyzed period 295 children (194 girls and 101 boys) aged between 6 months and 18 years were hospitalized due to acute drug poisoning. Nonopioid painkillers, antiepileptic drugs and sedatives, affecting the cardiovascular system were the main classes of ingested medications. A growing phenomenon of recreational use of drugs which induce euphoria, especially dextromethorphan, was observed among young people.. Due to rising incidence of drug poisoning in childhood physicians and pharmacists should extend their efforts to instruct and educate parents and caregivers about correct drag dosing, safe storage conditions and principles of poisoning prevention.

Dextromethorphan (DXM) is a derivative of codeine with an antitussive properties. Acute poisonings with this drug are related to serious, often life-threatening clinical symptoms. In the last decade the number of DXM poisonings increased and the problem was particularly noticeable among adolescents. The aim of this study was to analyze selected demographic and clinical parameters of patients who were hospitalized due to DXM poisoning in Pomeranian Centre of Toxicology between 2009-2011. The study included 170 individuals which was 2.7% of all admissions in this period. In 2009 and 2010, the proportion of patients poisoned with DXM did not exceed 1.5%, while in the years 2011- 2013 it tripled and reached up to 3.5%. The age of patients ranged from 12 to 42 (mean 18) years. Women were more frequently hospitalized. The dose of ingested DXM ranged from 150 to 2700 (mean 588.7) mg. The analysis revealed that the dose of ingested DXM was increasing with the age of patients.

Dextromethorphan is a widely available over-the-counter antitussive that produces intoxicating, hallucinogenic, and dissociative effects at doses significantly exceeding the therapeutic range. We report the deaths of five teenage males in three incidents in three states (WA, FL, and VA) who purposefully ingested large doses of dextromethorphan for recreational purposes and died as a result of the direct toxic effects of the drug. The dextromethorphan was obtained from the same internet supplier in each case. Postmortem blood dextromethorphan concentrations ranged from 950 to 3230 ng/mL (median 1890 ng/mL). Three subjects had diphenhydramine present, one had a trace of alprazolam, and two were positive for cannabinoids. In each case, the death was attributed to dextromethorphan toxicity or toxicity from dextromethorphan and other drugs. The article discusses the metabolism, pharmacology, and potential for drug interactions for dextromethorphan and the likely mechanisms for toxicity. The dextromethorphan concentrations in all five subjects significantly exceeded the therapeutic range and are consistent with concentrations reported in other cases of dextromethorphan abuse and toxicity. The deaths resulted in the prosecution of three individuals involved in sale or distribution of the drug.

The recreational usage of dextrometorphan, the popular antitussive medicine, has become alarming in Poland. The euphoric and hallucinogenic activity of this drug manifests after high doses, usually ranging from 225 to 1500 mg that may lead to acute poisoning. Currently, dextrometh-orphan is considered as addictive substance. In this article we describe the symptoms of acute dextrometorphan poisoning that have been observed in 11 patients, aged between 16 and 31 years that have been treated in the Department of Toxicology and Internal Diseases Raszeja Hospital in Poznan. In the course of intoxication the most frequent symptom was balance disturbation (12.50%), impaired motoric coordination (11.36%), confusion (11.36%) and papillary dilation (11.36%). Agitation (9.09%), tachycardia (7.95%), hallucinations (6.82%), disartria (5.68%) and hypertension (4.55%) were less common. The doses of dextromethorphan ranged from 4.28 to 16.67 mg/kg. All the patients were treated symptomatically. They recovered without sequelae and were discharged after 1-3 days of hospitalization.

The objective of this guideline is to assist poison center personnel in the appropriate out-of-hospital triage and initial out-of-hospital management of patients with a suspected ingestion of dextromethorphan by 1) describing the process by which an ingestion of dextromethorphan might be managed, 2) identifying the key decision elements in managing cases of dextromethorphan ingestion, 3) providing clear and practical recommendations that reflect the current state of knowledge, and 4) identifying needs for research. This guideline applies to the ingestion of dextromethorphan alone. Co-ingestion of additional substances could require different referral and management recommendations depending on the combined toxicities of the substances. This guideline is based on an assessment of current scientific and clinical information. The expert consensus panel recognizes that specific patient care decisions might be at variance with this guideline and are the prerogative of the patient and the health professionals providing care, considering all of the circumstances involved. This guideline does not substitute for clinical judgment. The grade of recommendation is in parentheses. 1) All patients with suicidal intent, intentional abuse, or in cases in which a malicious intent is suspected (e.g., child abuse or neglect) should be referred to an emergency department (Grade D). 2) Patients who exhibit more than mild effects (e.g., infrequent vomiting or somnolence [lightly sedated and arousable with speaking voice or light touch]) after an acute dextromethorphan ingestion should be referred to an emergency department (Grade C). 3) Patients who have ingested 5-7.5 mg/kg should receive poison center-initiated follow-up approximately every 2 hours for up to 4 hours after ingestion. Refer to an emergency department if more than mild symptoms develop (Grade D). 4) Patients who have ingested more than 7.5 mg/kg should be referred to an emergency department for evaluation (Grade C). 5) If the patient is taking other medications likely to interact with dextromethorphan and cause serotonin syndrome, such as monoamine oxidase inhibitors or selective serotonin reuptake inhibitors, poison center-initiated follow-up every 2 hours for 8 hours is recommended (Grade D). 6) Patients who are asymptomatic and more than 4 hours have elapsed since the time of ingestion can be observed at home (Grade C). 7) Do not induce emesis (Grade D). 8) Do not use activated charcoal at home.

A 30-year old woman was presented to the emergency room with marked lethargy and fever. Her physical examination showed an acneiform eruption on the face. Blood biochemistry showed a high chloride level and a negative anion gap. High blood bromide level measurements on an ion-selective electrode was noted later to cause spurious hyperchloremia with a negative anion gap. After receiving saline hydration and diuretic treatment, her serum chloride returned to normal range on hospital day nine. Slow resolution of her mental status occurred over 2 months. Her skin lesions disappeared about 5 months later. In conclusion, in face of an unusual high chloride level and a negative anion gap in a patient of long-term use of over-the-counter (OTC) agents, bromide intoxication should be included in the differential diagnosis.

Accidental ingestions of cough and cold preparations containing dextromethorphan (DM) are common in the toddler age group and rarely have serious consequences. Even large intentional overdoses by adults seldom lead to serious morbidity. There have been no previous reports of an extrapyramidal reaction due to a DM ingestion.. We report a 30-month-old girl who ingested approximately 38 mg/kg dextromethorphan. She presented with opisthotonus, ataxia, and bidirectional nystagmus. There was no change in her status with the administration of naloxone. The child was given diphenhydramine with clearing of her opisthotonus but persistence of her ataxia and nystagmus.. A moderate ingestion of dextromethorphan in a toddler resulted in extrapyramidal symptoms with opisthotonus that responded to diphenhydramine. Dextromethorphan is known to have complex CNS effects and, in sufficient doses, may have dopamine receptor blocking activity resulting in this dystonic reaction.

Because of rapid urbanisation in South Africa, scavenging from waste disposal sites by poor communities poses an increasing health risk. Reject cough lozenges, some of which contained larger amounts of dextromethorphan than usual, were illegally removed from a disposal site and, after resale by informal traders, caused moderately severe symptoms of toxicity in 171/540 (24%) primary school pupils. Although dextromethorphan was implicated as a cause, contributing effects of other toxins could not be excluded. Bacteriological cultures and a pesticide screen were negative. Had more toxic substances been involved, the consequences would have been disastrous. This incident supports calls for an integrated national waste management policy and waste control act to govern the management and control of waste from generation to disposal. Such a policy is necessary to prevent potentially serious incidents in the future.
