From the Guidelines
Morphine is not recommended for pain management in patients with End-Stage Renal Disease (ESRD) due to the risk of accumulation of its active metabolites, which can lead to toxicity. According to the Society for Perioperative Assessment and Quality Improvement (SPAQI) consensus statement published in the Mayo Clinic Proceedings in 2021 1, morphine, along with codeine and meperidine, should be avoided in patients with renal insufficiency (GFR <30 mL/min/1.73 m2) and ESRD due to the accumulation of active metabolites.
Key Considerations for ESRD Patients
- Opioids with no active metabolites, such as fentanyl, sufentanil, and methadone, are preferred for patients with renal insufficiency or ESRD 1.
- Hydrocodone, oxycodone, and hydromorphone can be used with caution and require dosage adjustments in renal insufficiency and ESRD 1.
- Non-opioid pain management strategies, including acetaminophen, adjuvant medications like gabapentin (with dose reduction), and non-pharmacological approaches, should also be considered to minimize opioid use.
Alternative Opioids for ESRD
- Fentanyl, hydromorphone, or oxycodone at reduced doses (typically 25-50% of normal dosing) are better alternatives for ESRD patients due to fewer active metabolites dependent on renal clearance.
- Methadone should be administered only by clinicians experienced in its use because of the risk of accumulation 1.
Monitoring and Dose Adjustments
- If morphine must be used in ESRD, the dose should be significantly reduced (by 50-75%), dosing intervals should be extended, and the patient should be closely monitored for signs of toxicity.
- Patients on dialysis may require additional dose adjustments, with supplemental doses potentially needed after dialysis sessions.
From the FDA Drug Label
Morphine pharmacokinetics are altered in patients with renal failure The AUC is increased, and clearance is decreased and the metabolites, M3G and M6G, may accumulate to much higher plasma levels in patients with renal failure as compared to patients with normal renal function. Morphine sulfate pharmacokinetics are altered in patients with renal failure. Start these patients with a lower than usual dosage of morphine sulfate tablets and titrate slowly while monitoring for signs of respiratory depression, sedation, and hypotension [see Clinical Pharmacology (12.3)].
Morphine is not ideal for patients with End-Stage Renal Disease (ESRD) due to altered pharmacokinetics.

From the Research
Pain Management in ESRD
- Pain management in patients with End-Stage Renal Disease (ESRD) is a complex task, and effective pain control improves quality of life 3.
- The World Health Organization's three-step analgesic ladder model is recommended for pain management in ESRD patients, with substitution or addition of opioid analgesics if pain control is not optimal 3.
Use of Morphine in ESRD
- Morphine is not recommended for use in ESRD patients due to the accumulation of potentially toxic metabolites 4.
- Alternative opioids such as fentanyl, methadone, and buprenorphine are considered safer options for pain management in ESRD patients 4, 5.
Safe Opioid Options for ESRD
- Opioids that are safer to use in kidney disease include oxycodone, hydromorphone, fentanyl, methadone, and buprenorphine 5, 6.
- Buprenorphine appears to be a promising and safer option due to its partial agonism at the mu opioid receptor 5.
Challenges in Pain Management
- Barriers to adequate pain management in ESRD patients include poor awareness of the problem, insufficient medical education, and fears of possible drug-related side effects 6, 7.
- A multidisciplinary approach is recommended for the management of complex pain syndromes in frail patients, such as those suffering from ESRD 6.
