- Insomnia
- Irritation and tremblings

5. Interactions and Contraindications
Lorazepam ought to not be taken in combination with other compounds that depress the central nerve system.

| Duration of Effect | 6-- 12 hours | 24-- 48+ hours | 6-- 12 hours |
| Metabolic process | Direct conjugation | Oxidative (Liver) | Oxidative (Liver) |
| Primary Use | Anxiety/Seizures | Muscle spasms/Seizures | Panic attacks/Anxiety |
6. Precautions for Specific Populations
Certain groups should work out severe caution when recommended lorazepam:
- The Elderly: Older adults are more conscious the sedative impacts, which substantially increases the danger of falls and hip fractures.
