Nandrol>55 y >50 yr)** | • Consider frailty; weigh benefits vs risks (e.g., osteoporosis, prostate issues).
• Prefer non‑hormonal interventions for mood/sedation when possible. | • More intensive monitoring: labs every 3–6 months.
• Regular bone density scans if long‑term use anticipated. |
| **Special Populations** | - *Post‑menopausal women*: monitor estrogenic effects, breast cancer risk.
- *Men with low testosterone*: consider baseline PSA and prostate imaging.
- *Individuals with liver disease*: avoid hepatotoxic formulations.
- *Elderly with cognitive impairment*: watch for confusion or delirium. | Tailored monitoring schedules per risk profile; adjust dosage accordingly. |

## 4. Clinical Decision‑Making Flowchart

Below is a simplified textual flowchart that clinicians can follow when considering prescription sleep aids in older adults. (For visual representation, convert this into a diagram with decision nodes.)

```
START
│
├─ Are there non-pharmacologic options already tried?
│ ├─ Yes → Implement CBT‑I / sleep hygiene; reassess after 4–6 weeks.
│ └─ No → Proceed to pharmacologic consideration.
│
├─ Does the patient have any contraindications (e.g., severe COPD, narrow-angle glaucoma, uncontrolled bradycardia)?
│ ├─ Yes → Avoid sedative-hypnotics; consider alternative strategies.
│ └─ No → Continue.
│
├─ Which pharmacologic agent is most appropriate?
│ │
│ ├─ Non-benzodiazepine hypnotic (e.g., zolpidem) if short-term use (3 months or worsens, refer to a sleep specialist.
```

### 5. Key Points

- Use CBT‑I as the first‑line treatment for chronic insomnia; medication is supplementary and should be short‑term.
- Consider benzodiazepines only if CBT‑I is unavailable or ineffective; monitor closely for side effects.
- Avoid long‑acting hypnotics (e.g., zolpidem) in patients with risk of tolerance, sedation, or falls.

### Final Recommendation

1. **Prescribe a short‑acting Z-drug (e.g., zolpidem 5 mg)** for 3–4 weeks, with clear instructions on dosing and safety precautions.
2. **If inadequate or if side‑effects occur**, consider switching to a lower‑dose hypnotic such as temazepam 1–2 mg at bedtime, ensuring the patient is fully informed about risks of daytime sedation and rebound insomnia.

This balanced approach maximizes efficacy for sleep onset while minimizing the risk profile associated with benzodiazepine hypnotics.
