End of Life Care Prescribing
๐ Principles of End-of-Life Prescribing
- ๐ฉโโ๏ธ Assess symptoms regularly and titrate doses to effect.
- ๐ Prefer subcutaneous (SC) route if oral not possible.
- ๐ฝ Anticipate side effects (e.g. constipation with opioids โ always prescribe laxatives).
- ๐ฉบ In renal impairment (eGFR <30), avoid morphine; consider oxycodone, fentanyl, or alfentanil.
- ๐ค Holistic care: communication with patient, family, and the wider MDT is essential.
๐ Symptom Management (without table)
- ๐ข Pain / Dyspnoea:
- Morphine 2.5โ5 mg SC PRN
- Oxycodone 1.25โ2.5 mg SC PRN (preferred in renal impairment)
- Consider continuous infusion if frequent PRN needed.
- ๐ต Agitation / Delirium:
- Midazolam 2.5โ5 mg SC PRN (good for anxiety/restlessness)
- Haloperidol 0.5โ1 mg SC PRN (less sedating).
- ๐ง Respiratory Secretions:
- Glycopyrronium 0.2 mg SC PRN (does not cross BBB โ less confusion)
- Hyoscine butylbromide 20 mg SC PRN.
- ๐คข Nausea / Vomiting:
- Haloperidol 0.5โ1 mg SC PRN (esp. opioid-induced nausea)
- Metoclopramide 10 mg SC PRN
- Cyclizine 50 mg SC every 8 hours.
- Choice guided by cause: metabolic vs gastric vs vestibular.
- โก Seizures:
- Midazolam 5โ10 mg SC stat
- Infusion: 20โ60 mg/24h
- Continue regular antiepileptics if possible.
๐ก Clinical Pearls
- ๐ Midazolam: short half-life, versatile (agitation, anxiety, seizures).
- ๐คข Haloperidol: gold standard antiemetic in palliative care (esp. opioid-induced nausea).
- ๐ด Levomepromazine: broad-spectrum antiemetic; sedating at higher doses, useful in refractory cases.
- ๐ง Glycopyrronium vs Hyoscine: Glycopyrronium preferred if confusion/delirium risk.
๐ฉบ Syringe Driver Tips
- ๐ Indicated when oral route not possible (vomiting, dysphagia, reduced consciousness).
- โ๏ธ Always check compatibility of mixes โ cyclizine often precipitates with opioids.
- ๐ Inspect syringe daily for cloudiness or crystallisation.
๐ Renal Impairment Summary
- ๐ซ Morphine: Avoid โ active metabolites accumulate and cause toxicity.
- โ ๏ธ Oxycodone: Use with caution; start low and titrate carefully.
- โ
Fentanyl / Alfentanil: Safe in severe renal impairment.
๐ง Teaching Pearl
๐ก In end-of-life care, the focus is on comfort, not cure.
๐ก Prescribe anticipatory medications early (pain, agitation, secretions, nausea, seizures) so symptoms can be managed promptly.
