Abstract
This review discusses risks, benefits, and alternatives in patients already taking benzodiazepines when care transfers to a new clinician. Prescribers have the decision-sometimes mutually agreed-upon and sometimes unilateral-to continue, discontinue, or change treatment. This decision should be made based on evidence-based indications (conditions and timeframes), comorbidities, potential drug-drug interactions, and evidence of adverse effects, misuse, abuse, dependence, or diversion. We discuss management tools involved in continuation (e.g., monitoring symptoms, laboratory testing, prescribing contracts, state prescription databases, stages of change) and discontinuation (e.g., tapering, psychotherapeutic interventions, education, handouts, reassurance, medications to assist with discontinuation, and alternative treatments).Entities:

Benzodiazepine risks, benefits, and alternatives.
| Risks | Benefits | Alternatives |
|---|---|---|
Physical adverse effects (e.g., commonly dizziness, slurred speech, and psychomotor impairment; most seriously overdose, withdrawal, falls, autonomic instability, seizures, hepatotoxicity, respiratory depression, and death) Cognitive adverse effects (e.g., commonly drowsiness, inattention; most seriously confusion, amnesia, hallucinations, delirium and coma) Emotional adverse effects (e.g., commonly depression, irritability, anxiety; most seriously lability) Behavioral adverse effects (e.g., commonly disinhibition, insomnia and avoidance; most seriously suicidality, violence and abuse) Other (e.g., teratogenicity, breast-feeding risks, drug-drug interactions) | Short-term anxiolytic effects Short-term hypnotic effects Fast-acting Can be prescribed as needed | Behavioral techniques Psychotherapy Sedating antidepressants (e.g., trazodone, mirtazapine, tricyclics) Adrenergic inhibitors (e.g., prazosin, propranolol) Antihistamines (e.g., hydroxyzine) Anticonvulsants (e.g., gabapentin, pregabalin) Antipsychotics (e.g., quetiapine, olanzapine, risperidone) Behavioral techniques Psychotherapy Serotonergic agents (e.g., antidepressants, buspirone) Antipsychotics Anticonvulsants (e.g., lamotrigine) |
