Associations between prescribed benzodiazepines, overdose death and buprenorphine discontinuation among people receiving buprenorphine. Benzodiazepines are commonly prescribed to patients with opioid use disorder receiving buprenorphine treatment, yet may increase overdose risk. However, prescribed benzodiazepines may improve retention in care by reducing buprenorphine discontinuation and thus
Acute fatal posthypoxic leukoencephalopathy following benzodiazepineoverdose: a case report and review of the literature. Among the rare neurological complications of substances of abuse is the selective cerebral white matter injury (leukoencephalopathy). Of which, the syndrome of delayed post hypoxic encephalopathy (DPHL) that follows an acute drug overdose, in addition to "chasing the dragon an acute severe fatal leukoencephalopathy following hypoxic coma and systemic shock induced by benzodiazepineoverdose. A 19-year-old male was found comatose at home and brought to hospital in a deep coma, shock, hypoxia, and acidosis. Brain magnetic resonant imaging (MRI) revealed a strikingly selective white matter injury early in the course of the disease. The patient remained in a comatose state
Serial monitoring of sedation scores in benzodiazepineoverdose. Benzodiazepines are widely used for many diseases, and benzodiazepineoverdose is globally increasing in proportion to its prescriptions. Although most benzodiazepineoverdoses are known to be safe and nonfatal without coingestions, morbidity or mortality after benzodiazepineoverdose is closely related with the duration of unconsciousness or depth of compromised airway. Proper use of flumazenil, a potent antidote of benzodiazepine, seems to accelerate the recovery from the toxicity after benzodiazepine overdose.However, as the case we present demonstrates, careful attention and repetitive evaluations before and after use of flumazenil may be needed in benzodiazepineoverdose because resedation occurs in approximately 30% of total
as a “diagnostic” agent. Use with caution in patients with benzodiazepine poisoning, particularly in mixed drug overdoses; contraindicated in mixed tricyclic antidepressant / benzodiazepineoverdoses and in those with a history of epilepsy.

of accidental overdose, especially when combined with other substances that suppress breathing and heart rate such as other opioids or benzodiazepines. • Overdoses involving nitazenes may be difficult to reverse, potentially requiring additional doses of naloxone, but protocols around this are not yet clear. • Fentanyl test strips cannot detect nitazenes, and detection of nitazenes by point-of -service drug
as benzodiazepineoverdose is seldom fatal and fl umazenil has side effects (pg 130).Grade A, Level 1+A Flumazenil is not recommended in patients with epilepsy, benzodiazepine dependence or suspected multi-agent overdoses. Co-ingested substances, such as heterocyclic antidepressants, are known to produce seizures (pg 130). Grade A, Level 1+Selective serotonin reuptake inhibitor (SSRI)D Asymptomatic patients
for the treatment of benzodiazepineoverdoses. In epileptogenic regions a reduced level of benzodiazepine receptors was found by some authors [158], others reported false lateralization [159]. The PET radioligand [11C]flumazenil ([11C]FMZ) is selective for the GABA-A receptor subunits α1–3 and α5 [160]. [11C]FMZ binding is reduced in the hippocampi and other temporal lobe regions of individuals with refractory
screen positive for barbiturates does not prove that the drug caused the patient’s clinical condition. Serum barbiturate levels confirm the diagnosis, but do not correlate well with depth of coma or clinical outcome. * Flumazenil is not indicated in the majority of benzodiazepineoverdoses, particularly not in regular benzodiazepine users, in whom flumazenil can precipitate seizures. Because , delirium, seizures [8] What are the indications for flumazenil? What are the contraindications? (box 159.2)Indications * Isolated benzodiazepineoverdose in non-habituated user (eg.

Association of Benzodiazepine Treatment for Sleep Disorders With Drug Overdose Risk Among Young People. Benzodiazepines are prescribed for the treatment of adolescent sleep disorders; however, benzodiazepineoverdoses occur, often in combination with opioids. To evaluate whether benzodiazepine treatment for sleep disorders, compared with alternative pharmacologic treatments (trazodone

explained that this may be due to higher disease severity associated with benzodiazepine prescribing and/or increased risk for benzodiazepineoverdose. The analysis also showed that antidepressants and/or psychotherapy treatments lessened the odds for suicide death among those with 3–8 benzodiazepine dispensings compared to those who used benzodiazepines as monotherapy. • There is insufficient evidence
