From the Guidelines
For a 97-year-old female with insomnia, non-medication approaches should be tried first, such as maintaining regular sleep schedules, limiting daytime napping, avoiding caffeine and alcohol before bedtime, and creating a comfortable sleep environment. If medications are necessary, low-dose melatonin (0.5-1mg) taken 1-2 hours before bedtime is often the safest initial choice, as supported by the American College of Physicians guideline 1. If this is ineffective, very low doses of trazodone (25mg) or mirtazapine (7.5mg) at bedtime may be considered for short-term use, but with caution due to their potential side effects 1. Avoid benzodiazepines and "Z-drugs" like zolpidem or eszopiclone as they significantly increase fall risk, confusion, and cognitive impairment in the elderly, as warned by the FDA and highlighted in the 2019 U.S. Department of Veterans Affairs and U.S. Department of Defense clinical practice guidelines 1. Antihistamines like diphenhydramine should also be avoided due to anticholinergic side effects, as recommended against in the 2019 Beers Criteria 1. Any medication should be started at the lowest possible dose, used for the shortest duration possible, and regularly reassessed for effectiveness and side effects, following a "start low, go slow" approach 1. The elderly metabolize medications more slowly and are more sensitive to side effects, so it is essential to monitor them closely and adjust treatments as needed, considering their complete medical history and medication list to avoid harmful interactions 1.
Some key points to consider when treating insomnia in the elderly include:
- Non-medication approaches should be the first line of treatment
- Low-dose melatonin is a safer initial choice for medication
- Benzodiazepines and "Z-drugs" should be avoided due to increased risk of falls and cognitive impairment
- Antihistamines should be avoided due to anticholinergic side effects
- Medications should be started at the lowest possible dose and used for the shortest duration possible
- Regular reassessment of medication effectiveness and side effects is crucial
- A "start low, go slow" approach is essential when prescribing medications to the elderly.
From the FDA Drug Label
Normal elderly adults (mean age 68) experiencing transient insomnia (n=35) during the first two nights in a sleep laboratory were evaluated in a double-blind, crossover, 2-night trial comparing four doses of zolpidem (5,10,15 and 20 mg) and placebo All zolpidem doses were superior to placebo on the two primary PSG parameters (sleep latency and efficiency) and all four subjective outcome measures (sleep duration, sleep latency, number of awakenings, and sleep quality). There was subjective evidence of impaired sleep in the elderly on the first post-treatment night at doses above the recommended elderly dose of 5 mg
The best medication for insomnia in a 97-year-old female is not directly stated in the provided drug labels. However, based on the available information, zolpidem at a dose of 5 mg may be considered, as it is the recommended dose for elderly patients.
- Key considerations:
- The patient's age is significantly higher than the mean age of the elderly adults in the studies (68 years).
- The recommended dose for elderly patients is 5 mg, and doses above this may cause impaired sleep or anterograde amnesia.
- The studies did not evaluate the safety and efficacy of zolpidem in patients older than 68 years. 2 2
From the Research
Medications for Insomnia in a 97-Year-Old Female
The treatment of insomnia in older adults, particularly those as old as 97, requires careful consideration due to the potential for increased sensitivity to medications and the higher risk of adverse effects.
- Benzodiazepines and Nonbenzodiazepines: These are commonly used for insomnia but are generally discouraged in the geriatric population due to risks such as dementia, serious injury, and fractures 3, 4.
- Trazodone and Melatonin: These are often considered for older adults with insomnia. Trazodone is an antidepressant that can help with sleep, and melatonin is a hormone that regulates sleep-wake cycles. Both have been studied for their safety and efficacy in older populations 5, 6.
- Ramelteon: This medication has a minimal adverse effect profile and is effective for sleep-onset latency and increasing total sleep time, making it a valuable option for older adults 4.
- Suvorexant: Although data is limited, suvorexant improves sleep maintenance with mild adverse effects, including somnolence. However, residual daytime sedation has been reported 4.
- Valerian: This is an unregulated product with a small impact on sleep latency and can produce residual sedation. Its use in older adults should be approached with caution 4.
Considerations for Treatment
When selecting a medication for insomnia in a 97-year-old female, it's crucial to:
- Start with a low dose and monitor the patient carefully for side effects 3.
- Consider non-pharmacological interventions as the first line of treatment, including cognitive behavioral therapy for insomnia (CBT-I) and sleep hygiene practices 4.
- Be aware of potential interactions with other medications the patient may be taking.
- Regularly review and adjust the treatment plan as necessary to minimize the risk of adverse effects and ensure the medication remains effective 4, 6.
