Sublingual Ativan Dissolved in Liquid Morphine for End-of-Life Care
Yes, it is appropriate to co-administer sublingual lorazepam (Ativan) with liquid morphine as a slurry for patients nearing end of life, as both medications are commonly used together in palliative care settings to manage refractory symptoms including pain, dyspnea, and agitation. 1
Rationale for Combined Administration
The combination of lorazepam and morphine is well-established in end-of-life care:
- Both medications are recommended for emergency sedation to provide urgent relief of overwhelming symptoms in dying patients, including severe terminal dyspnea, overwhelming pain crisis, and terminal restlessness 1, 2
- Research demonstrates that adding morphine to lorazepam significantly improves sedation and relief of anxiety compared to lorazepam alone 3
- As swallowing function diminishes in the dying process, medications are typically administered sublingually, transdermally, or via rectal suppository 4
Practical Administration Considerations
When creating a slurry for sublingual administration:
- The sublingual route is appropriate as patients lose swallowing ability near end of life 4
- Lorazepam tablets can be crushed and mixed with liquid morphine for combined administration 5
- This approach allows for simultaneous delivery of both anxiolytic/sedative and analgesic effects
Dosing Framework
For end-of-life symptom management:
- Standard lorazepam dosing ranges from 1-2 mg for elderly or debilitated patients, adjustable as needed 6
- Morphine dosing should target adequate pain and dyspnea control 4
- The lowest effective dose should be used to provide adequate comfort while monitoring for distress 1
Synergistic Benefits
The combination offers multiple therapeutic advantages:
- Morphine provides control of pain and dyspnea, which are common symptoms in the dying process 4
- Lorazepam addresses anxiety, agitation, and terminal restlessness 2, 7
- Combined therapy enhances sedation and anxiety relief beyond either agent alone 3
Important Caveats
Monitor for potential complications:
- The combination may cause additive respiratory depression, though comfort remains the primary goal in end-of-life care 1
- Restlessness can occur in 3-15% of patients receiving lorazepam, independent of morphine addition 3
- For patients at home at risk of catastrophic events, sedating medications should be prepared in advance with a clear emergency administration plan 1
Clinical Decision-Making
The intent and goals must be clearly established:
