Whole fentanyl patch ingestion: a multi-center case series.
BACKGROUND: Fentanyl is a potent synthetic opioid with large abuse potential. A common preparation of fentanyl is a sustained-release transdermal patch. To our knowledge, there are only two published case reports of whole patch ingestion. A case series of 76 patients with a history of whole patch ingestion is reported.
STUDY OBJECTIVES: To characterize whole fentanyl patch ingestion to develop a clinical guideline for management.
METHODS: This was a retrospective review of all patients who ingested intact fentanyl patches as reported to three regional poison information centers (RPIC) from 2000 to 2008. The three RPIC medical record databases were queried for all exposures with a substance code matching the Micromedex® (Thomson Reuters, New York, NY) fentanyl product codes. Collected data included: age, gender, reason for the exposure, number of patches ingested, dose (μg/h), symptoms, symptom onset and duration, treatment hospital flow (level of care), and outcome.
RESULTS: A total of 76 patients met the inclusion criteria. Two patients had both time of onset and symptom duration documented. In both patients, the signs and symptoms developed within 2 h of the exposure, and the patients were asymptomatic at 6½ and 9 h, respectively. Fifty-eight (78.3%) patients were admitted. Of those patients who were admitted, 56 (96.5%) were admitted to a critical care unit. Fourteen patients required intubation, and naloxone infusions were documented in eight cases.
CONCLUSION: Ingestion of whole fentanyl patches may lead to prolonged and significant toxicity based on these poison center data
The Potential Role of an Extended-Release, Abuse-Deterrent Oxycodone/Acetaminophen Fixed-Dose Combination Product for the Treatment of Acute Pain
Should methionine be added to every paracetamol tablet?
Paracetamol is commonly used for self poisoning, and the costs of treating the resulting liver failure in the few who develop it are high. The morbidity could be avoided by adding methionine to paracetamol tablets, but this would mean that the millions of people who take paracetamol responsibly would have to take methionine unnecessarily. Alison Jones and colleagues and Edward Krenzelok debate the issue
Surveillance of Diversion and Nonmedical Use of Extended-Release Prescription Amphetamine and Oral Methylphenidate in the United States
This article examines rates of nonmedical use and diversion of extended-release amphetamine and extended-release oral methylphenidate in the United States. Prescription dispensing data were sourced from retail pharmacies. Nonmedical use data were collected from the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS) System Drug Diversion Program and Poison Center Program. Drug diversion trends nearly overlapped for extended-release amphetamine and extended-release oral methylphenidate. Calls to poison centers were generally similar; however, calls regarding extended-release amphetamine trended slightly lower than those for extended-release oral methylphenidate. Data suggest similar diversion and poison center call rates for extended-release amphetamine and extended-release oral methylphenidate
