Why Ativan (Lorazepam) Is Problematic

Lorazepam is not a good idea for most patients because benzodiazepines cause delirium, cognitive impairment, falls with serious injury risk, and lead to dependence—harms that typically outweigh benefits except in specific circumstances like alcohol/benzodiazepine withdrawal or end-of-life crisis management.

Primary Concerns with Lorazepam

Delirium Risk

• Benzodiazepines are themselves deliriogenic, meaning they directly cause or worsen delirium rather than treating it 1
• The ESMO guidelines explicitly state that benzodiazepines "are not considered part of the initial strategy in delirium management" because they are sedating, identified as deliriogenic, and associated with clear fall risk 1
• Lorazepam may cause paradoxical agitation, drowsiness, and delirium as direct adverse effects 1

Cognitive Impairment and Falls

• Regular benzodiazepine use leads to tolerance, addiction, depression, and cognitive impairment 1
• Lorazepam carries an increased risk of falls, particularly dangerous in older, frail patients, or those with COPD 1
• The Mayo Clinic guidelines classify benzodiazepines as medications requiring deprescribing in older adults due to sedation, cognitive impairment, unsafe mobility with injurious falls, and motor skill impairment 1

Dependence and Withdrawal

• Physical dependence develops with continued use, and abrupt discontinuation can precipitate life-threatening acute withdrawal reactions including seizures 2
• The FDA label warns that lorazepam exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death 2
• Some patients develop protracted withdrawal syndrome with symptoms lasting weeks to over 12 months 2

Respiratory Depression

• Benzodiazepines may lead to potentially fatal respiratory depression, especially when combined with other CNS depressants 2
• This risk is particularly elevated in patients with severe pulmonary insufficiency, severe liver disease, or when co-administered with antipsychotics 1

Limited Appropriate Indications

Lorazepam has only narrow, specific roles:

• First-line treatment for alcohol or benzodiazepine withdrawal (though short-acting agents like oxazepam are preferred in cirrhotic patients) 1
• Crisis intervention in end-of-life care for severe agitation and distress in delirious patients, but only after careful assessment of distress level, safety risks, and patient mobility 1
• Short-term management of severe anxiety when non-pharmacologic approaches have failed 1

Common Pitfalls to Avoid

• Do not use lorazepam for routine anxiety or insomnia management—cognitive behavioral therapy and non-benzodiazepine alternatives are preferred 1
• Avoid in patients with dementia or cognitive disorders—benzodiazepines worsen cognitive function and carry an FDA black box warning for increased mortality risk in dementing disorders 1
• Never prescribe long-term without a clear exit strategy—if prescribed, use the lowest effective dose for the shortest duration, with a gradual taper plan 2
• Do not combine with high-dose olanzapine—fatalities have been reported 1
• Recognize paradoxical agitation occurs in approximately 10% of patients treated with benzodiazepines 1

Safer Alternatives

For most clinical scenarios where lorazepam might be considered:

• Anxiety disorders: SSRIs, SNRIs, buspirone, or cognitive behavioral therapy 1
• Insomnia: Non-benzodiazepine hypnotics (eszopiclone, zolpidem), low-dose sedating antidepressants, or sleep restriction therapy 1
• Delirium: Atypical antipsychotics (olanzapine, quetiapine, aripiprazole) for symptomatic management, with focus on treating underlying causes 1
• Agitation in dementia: Redirection, environmental modifications, and if necessary, atypical antipsychotics at lowest effective doses 1
