Ketorolac Use in Patients with Renal Impairment

Introduction to Ketorolac Contraindications

• The National Comprehensive Cancer Network recommends opioid analgesics as safer and effective alternatives to NSAIDs for patients with renal impairment 1
• The American Society of Clinical Oncology suggests methadone as an appropriate option for patients with cancer pain and renal impairment, as it is primarily excreted through fecal routes rather than renal elimination 2

Monitoring and Management

• The National Comprehensive Cancer Network guidelines recommend monitoring blood pressure, BUN, creatinine, and liver function tests at baseline and every 3 months in patients with renal impairment who require NSAID use 1
• The guidelines also suggest discontinuing NSAID use immediately if BUN or creatinine doubles or if hypertension develops or worsens 1
• Limiting the duration of NSAID use to the absolute minimum necessary is recommended, with ketorolac generally limited to 5 days maximum use even in healthy patients 1

Alternative Pain Management Strategies

• Acetaminophen (without NSAIDs) may be an appropriate option for mild analgesia in patients with renal impairment, with proper dosing 1
• Methadone is a suitable alternative for patients with cancer pain and renal impairment, due to its primary excretion through fecal routes rather than renal elimination 2
