Can I give my patient a Toradol (ketorolac) injection if they took ibuprofen this morning?

Avoid Administering Toradol After Ibuprofen Use

You should not administer a Toradol (ketorolac) injection to a patient who took ibuprofen this morning due to the contraindication of concurrent NSAID use, which significantly increases the risk of serious adverse events. 1

Rationale for Avoiding Concurrent NSAID Use

• Ketorolac (Toradol) is explicitly contraindicated in patients currently receiving aspirin or other NSAIDs (including ibuprofen) due to cumulative risks of inducing serious NSAID-related adverse events 1
• The American Geriatrics Society recommends using only one NSAID at the lowest effective dose for the shortest duration possible to minimize risks 2
• Combined use of ibuprofen and ketorolac significantly increases the risk of:
  • Gastrointestinal bleeding and perforation 2
  • Acute kidney injury 2
  • Cardiovascular thrombotic events 2

Timeframe Considerations

• Ibuprofen has a half-life of approximately 2-4 hours, but its effects on platelet function and COX inhibition can persist longer 2
• Ketorolac should not be administered until ibuprofen has been fully cleared from the system, which typically takes 4-6 half-lives (approximately 8-24 hours) 3

Alternative Pain Management Options

If the patient requires immediate pain management, consider these alternatives:

• Acetaminophen (if not already at maximum daily dose) 4
• Tramadol (if appropriate for pain severity) 4
• Opioid analgesics for short-term use if severe pain warrants 4
• For patients with osteoarthritis pain specifically, intra-articular corticosteroid injections may be considered 4

Special Considerations

• If the patient is also taking low-dose aspirin for cardioprotection, be aware that ibuprofen can interfere with aspirin's cardioprotective effects 4
• For elderly patients (>60 years), the risks of adverse events from either NSAID are substantially higher, and special caution should be exercised 2
• Patients with history of cardiovascular disease, renal impairment, or GI disorders are at particularly high risk for complications from concurrent NSAID use 2

Monitoring Requirements if NSAIDs Must Be Used

If pain management absolutely requires NSAID therapy after the appropriate waiting period:

• Monitor blood pressure, BUN, creatinine, liver function tests, and for signs of GI bleeding 2
• Consider co-prescribing a proton pump inhibitor to reduce GI complication risk 2
• Limit ketorolac treatment to no more than 5 days due to increased toxicity risk with prolonged use 3

Documentation

Document clearly in the patient's chart:

• The patient's recent ibuprofen use
• The decision to withhold ketorolac due to contraindication
• Alternative pain management strategy implemented
• Patient education provided regarding NSAID risks
