From the Guidelines
For patients undergoing dialysis with impaired renal function, recommended IV pain medications include fentanyl, hydromorphone, and sufentanil as first-line opioid options. These medications undergo minimal renal elimination and have fewer active metabolites that could accumulate in renal failure 1. Fentanyl can be dosed at 25-50 mcg IV every 1-2 hours as needed, while hydromorphone is typically given at 0.2-0.4 mg IV every 2-4 hours, with dose reductions of 25-50% from standard dosing. Non-opioid options include IV acetaminophen (1000 mg every 6 hours, not exceeding 3000 mg daily) and certain NSAIDs for short durations with careful monitoring. Some key points to consider when managing pain in patients with renal impairment include:
- Avoiding medications that produce active metabolites, such as morphine and meperidine, which can accumulate in renal failure and cause neurotoxicity and prolonged sedation 1
- Using opioids with no active metabolites, such as fentanyl and sufentanil, which are preferred for patients with renal insufficiency or end-stage renal disease (ESRD) 1
- Careful titration of opioids, starting with lower doses and extending dosing intervals while monitoring for side effects 1
- Reassessing pain management frequently, particularly after dialysis sessions, which may clear some medications and require dose adjustments to maintain adequate pain control 1 It's also important to note that the management of pain in patients with renal impairment requires a comprehensive approach, taking into account the patient's individual needs and medical history 1.
From the FDA Drug Label
Ketorolac tromethamine is contraindicated in patients with serum creatinine concentrations indicating advanced renal impairment Ketorolac tromethamine should be used with caution in patients with impaired renal function or a history of kidney disease because it is a potent inhibitor of prostaglandin synthesis Because patients with underlying renal insufficiency are at increased risk of developing acute renal decompensation or failure, the risks and benefits should be assessed prior to giving ketorolac tromethamine to these patients.
The recommended IV pain medication for patients undergoing dialysis due to impaired renal function is not explicitly stated in the provided drug labels. Ketorolac is contraindicated in patients with advanced renal impairment and should be used with caution in patients with impaired renal function.
- Alternative therapies that do not involve NSAIDs should be considered for high-risk patients, including those with impaired renal function.
- The use of ketorolac in patients with impaired renal function should be carefully weighed against the risks, and patients should be closely monitored 2.

IV Pain Medications for Dialysis Patients
The following IV pain medications are recommended for patients undergoing dialysis due to impaired renal function:
- Fentanyl: considered safe for use in patients with renal impairment 3, 4, 5
- Alfentanil: recommended for use in patients with renal impairment 3, 4
- Methadone: can be used safely in patients with renal impairment, but with caution and close monitoring 3, 4, 6, 5
- Buprenorphine: considered a safe choice for patients with reduced renal function, including those undergoing haemodialysis 4, 6, 7
- Hydromorphone: can be used with caution and reduced dose in patients with renal impairment 4, 6, 5
- Oxycodone: can be used with caution and reduced dose in patients with renal impairment 4, 6, 5
- Tramadol: can be used with caution and reduced dose in patients with renal impairment 3, 4, 6
