Absolute Contraindications to IV Ketorolac for Acute Pain

Do not administer IV ketorolac to patients with active peptic ulcer disease, recent GI bleeding/perforation, history of peptic ulcer disease or GI bleeding, advanced renal impairment, suspected cerebrovascular bleeding, hemorrhagic diathesis, incomplete hemostasis, pregnancy/labor, or those scheduled for CABG surgery. 1

Critical Contraindications from FDA Labeling

The FDA drug label 1 provides explicit contraindications that must be strictly observed:

Gastrointestinal Contraindications

  • Active peptic ulcer disease (absolute contraindication)
  • Recent GI bleeding or perforation (absolute contraindication)
  • History of peptic ulcer disease or GI bleeding (absolute contraindication)
  • Elderly patients face substantially higher risk for serious GI events 1

Renal Contraindications

  • Advanced renal impairment (absolute contraindication)
  • Patients at risk for renal failure due to volume depletion (absolute contraindication)
  • Hypovolemia must be corrected before ketorolac administration 1
  • In pediatric cardiac surgery populations, ketorolac caused acute kidney injury in infants with preexisting renal dysfunction 2

Bleeding/Hematologic Contraindications

  • Suspected or confirmed cerebrovascular bleeding (absolute contraindication)
  • Hemorrhagic diathesis (absolute contraindication)
  • Incomplete hemostasis (absolute contraindication)
  • High risk of bleeding (absolute contraindication)
  • Prophylactic use before any major surgery (absolute contraindication) 1

Cardiovascular Contraindications

  • Coronary artery bypass graft (CABG) surgery setting (absolute contraindication) 1
  • NSAIDs including ketorolac increase risk of serious cardiovascular thrombotic events, MI, and stroke 3, 1

Hypersensitivity Contraindications

  • Previous hypersensitivity to ketorolac (absolute contraindication)
  • Asthma, urticaria, or allergic reactions after aspirin or other NSAIDs (absolute contraindication)
  • Severe, rarely fatal anaphylactic reactions have occurred 1

Obstetric Contraindications

  • Labor and delivery (absolute contraindication - may adversely affect fetal circulation and inhibit uterine contractions) 1
  • Pregnancy (contraindication per migraine guideline) 4

Drug Interaction Contraindications

  • Concomitant aspirin or NSAID use (absolute contraindication due to cumulative risk) 1
  • Concomitant probenecid (absolute contraindication) 1
  • Concomitant pentoxifylline (absolute contraindication) 1

Route-Specific Contraindications

  • Neuraxial (epidural or intrathecal) administration (absolute contraindication due to alcohol content) 1

Special Populations Requiring Caution or Dose Adjustment

While not absolute contraindications, these populations require careful consideration and modified dosing 1:

  • Age ≥65 years: Maximum 15 mg IV per dose, not to exceed 60 mg/day (versus 30 mg per dose/120 mg per day for younger patients)
  • Body weight <50 kg (110 lbs): Same reduced dosing as elderly
  • Moderately elevated serum creatinine: Same reduced dosing as elderly
  • Pediatric patients with single-ventricle palliation: Use with extreme caution due to acute kidney injury risk 2
  • Concomitant aspirin use: Increases bleeding risk 2.5-fold when combined with therapeutic anticoagulation 5

Critical Prescribing Limitations

Maximum duration: 5 days total (combined IV/IM and oral ketorolac) 1. The 2002 migraine guideline 4 explicitly states treatment should not exceed 5 days, and the FDA label reinforces this across all indications. Prolonged therapy beyond 5 days substantially increases adverse event risk 6.

Common Pitfalls to Avoid

  1. Do not use ketorolac prophylactically before surgery - this is an absolute contraindication often overlooked 1
  2. Do not assume "one-time dose" exempts you from contraindications - even single doses carry risk in contraindicated populations 7
  3. Do not combine with other NSAIDs or aspirin - cumulative toxicity is contraindicated 1
  4. Do not administer without correcting hypovolemia first - renal failure risk 1
  5. Do not exceed 5-day total duration regardless of route 1

The evidence strongly supports that ketorolac provides effective analgesia comparable to opioids 8, 9, 10, but only when used in appropriately selected patients without contraindications. The risk-benefit calculation fundamentally changes in the presence of any absolute contraindication listed above.
