Transitioning a 74-Year-Old Woman from Lorazepam to Temazepam: A Critical Safety Protocol
Do not transition this patient to temazepam—instead, implement a gradual lorazepam taper to complete discontinuation while addressing her alcohol use and insomnia with evidence-based non-pharmacologic and safer pharmacologic alternatives. 1
Why Temazepam Is Not the Solution
- The American Geriatrics Society explicitly recommends avoiding all benzodiazepines—including both lorazepam and temazepam—in older adults due to markedly increased risks of cognitive impairment, delirium, falls, fractures, motor-vehicle crashes, and dementia. 1
- Switching from one benzodiazepine to another does not reduce harm; it perpetuates the same risks while complicating the clinical picture. 1, 2
- After 15 years of nightly lorazepam, this patient has established physical dependence; substituting temazepam will maintain that dependence and delay the only intervention proven to improve long-term outcomes: complete benzodiazepine discontinuation. 1, 3
- Temazepam carries identical risks to lorazepam in elderly patients—cognitive decline, falls, respiratory depression when combined with alcohol, and paradoxical agitation in approximately 10% of elderly patients. 1, 4
The Correct Clinical Approach: Gradual Lorazepam Taper
Step 1: Address Concurrent Alcohol Use First
- Benzodiazepine withdrawal carries greater risk than opioid withdrawal and must never be attempted while the patient continues nightly alcohol consumption (half-bottle of wine ≈ 2–3 standard drinks). 2
- Concomitant alcohol and benzodiazepine use dramatically increases respiratory depression risk, cognitive impairment, and fall risk; this combination must be addressed before any taper begins. 4
- Refer the patient for alcohol-use assessment and brief intervention; consider involving addiction medicine or psychiatry if she meets criteria for alcohol use disorder. 2
- Once alcohol intake is stable or eliminated, proceed with benzodiazepine taper; attempting both simultaneously obscures the source of withdrawal symptoms and increases failure risk. 1
Step 2: Lorazepam Taper Protocol
- Reduce lorazepam by 25% of the current dose every 1–2 weeks for patients on benzodiazepines less than 1 year; for this patient with 15 years of use, slow to 10% of the current dose per month to minimize withdrawal symptoms. 1, 2
- Example taper schedule (assuming current dose is 2 mg nightly):
- Total expected taper duration: 16–20 months minimum; some patients require up to several years. 1, 2
- Abrupt discontinuation can precipitate seizures and death—never stop suddenly. 1, 2, 5
Step 3: Monitoring During Taper
- Weekly visits during the first 8 weeks, then every 2 weeks thereafter. 1
- At each visit, assess for withdrawal symptoms: anxiety, tremor, insomnia, sweating, tachycardia, headache, weakness, muscle aches, nausea, confusion, and seizures. 1, 2
- If significant withdrawal symptoms appear, slow the taper or pause for 2–4 weeks before continuing. 1, 2
- Monitor for re-emergence of insomnia, anxiety, or depression; screen for substance use disorders at each visit. 1, 2
Step 4: Adjunctive Pharmacologic Support
- Gabapentin 100–300 mg at bedtime, titrated as tolerated, may lessen withdrawal symptoms. 1, 2
- Typical gabapentin titration: start 100–300 mg nightly, increase by 100–300 mg every 1–7 days as tolerated; adjust dose in renal insufficiency. 2
- Do not substitute another benzodiazepine or Z-drug (zolpidem, zaleplon, eszopiclone) for lorazepam, as they carry comparable risks in older adults. 1, 6
Evidence-Based Insomnia Management During and After Taper
First-Line Non-Pharmacologic Therapy (Essential)
- Cognitive Behavioral Therapy for Insomnia (CBT-I) is the standard of care for chronic insomnia, offering superior long-term efficacy compared with medications and preserving benefits after drug discontinuation. 7, 6
- Integrating CBT-I during the benzodiazepine taper significantly increases success rates and reduces relapse risk. 1, 2, 3
- Core CBT-I components: stimulus control (leave bed when unable to sleep within 20 minutes), sleep restriction (time in bed = actual sleep + 30 minutes), relaxation techniques (progressive muscle relaxation), and cognitive restructuring of maladaptive sleep beliefs. 7, 6
- CBT-I can be delivered via individual therapy, group sessions, telephone-based programs, or web-based modules. 6
Sleep Hygiene Education
- Establish a predictable daily routine with consistent bedtimes and wake times. 1, 6
- Limit daytime naps to a single 15–20 minute nap before 3 PM. 6
- Avoid caffeine after noon and eliminate alcohol in the evening. 6
- Do not eat heavy meals within 3 hours of bedtime. 6
- Create a comfortable sleep environment (earplugs, eye-shades, noise/light reduction). 6
Safer Pharmacologic Alternatives (If Non-Pharmacologic Measures Insufficient)
- Low-dose doxepin (3–6 mg at bedtime) is the preferred first-line hypnotic for older adults with sleep-maintenance insomnia who are tapering benzodiazepines. 6
- Moderate-quality evidence shows low-dose doxepin reduces wake after sleep onset by approximately 22–23 minutes, improves sleep efficiency, total sleep time, and overall sleep quality, with minimal anticholinergic activity at this dose. 6
- Low-dose doxepin has no abuse potential, is not a controlled substance, and carries no black-box warnings. 6
- Ramelteon 8 mg shortens sleep-onset latency without abuse potential or withdrawal symptoms; appropriate for difficulty falling asleep. 7, 6
- Suvorexant 10 mg (not 20 mg) decreases wake after sleep onset by 16–28 minutes and carries lower risk of cognitive and psychomotor impairment than benzodiazepine-type agents. 7, 6
Medications to Avoid
- Trazodone is not recommended for insomnia in older adults because it yields only ~10 minutes reduction in sleep latency, does not improve subjective sleep quality, and produces adverse events in roughly 75% of this population. 6
- Over-the-counter antihistamines (diphenhydramine, doxylamine) lack efficacy for insomnia and cause pronounced anticholinergic side-effects (confusion, urinary retention, falls, delirium); they should be avoided. 6
- Antipsychotics (quetiapine, olanzapine) carry a black-box warning for roughly two-fold increase in mortality in older adults and should not be used for insomnia. 6
Expected Outcomes and Timeline
- Total deprescribing period: 16–20 months minimum for lorazepam taper. 1
- Successful withdrawal typically yields improved psychomotor and cognitive function, especially memory and daytime alertness. 1, 3
- Reduced sedation is usually noticeable within 2–4 weeks after completing the lorazepam taper. 1
- When reversible benzodiazepine-induced toxicity is present, cognitive function typically improves within weeks to months after drug cessation. 1
Common Pitfalls to Avoid
- Never substitute another benzodiazepine or Z-drug for lorazepam; this perpetuates the same risks and delays definitive treatment. 1, 2
- Never taper lorazepam and address alcohol use simultaneously; this obscures the source of emerging symptoms. 1
- Do not abandon the patient if tapering fails; maintain therapeutic relationship and consider low-dose maintenance as an acceptable outcome. 1, 2
- Avoid straight-line reductions from the starting dose; always reduce by a percentage of the current dose to prevent disproportionately large final decrements. 1, 2
- Never taper too quickly; research shows that even a 10% reduction every 3 days resulted in only 24% of patients completing withdrawal successfully. 2
Referral Criteria
- History of withdrawal seizures from prior benzodiazepine cessation. 1, 2
- Unstable psychiatric comorbidities (e.g., severe depression, suicidal ideation). 1, 2
- Previous unsuccessful office-based taper attempts. 1, 2
- Co-occurring substance use disorders (including alcohol use disorder). 2
- Patient refuses to taper or is unable to tolerate even minimal dose reductions. 2
Bottom Line
Switching from lorazepam to temazepam in a 74-year-old woman with 15 years of nightly benzodiazepine use and concurrent alcohol consumption is clinically inappropriate and perpetuates harm. 1 The evidence-based approach is a gradual lorazepam taper (10% of current dose per month) combined with alcohol cessation support, CBT-I, and—if pharmacotherapy is needed—low-dose doxepin 3–6 mg or ramelteon 8 mg. 1, 2, 6 This strategy reduces fall risk, cognitive impairment, and mortality while addressing the root cause of her insomnia through non-pharmacologic means. 1, 6, 3
