Can Ketorolac Be Given?
Yes, ketorolac can be given for short-term management of moderately severe acute pain requiring opioid-level analgesia, but only for a maximum of 5 days and with careful attention to multiple absolute contraindications and high-risk populations. 1
Absolute Contraindications
Ketorolac is contraindicated in the following situations and must not be given 1, 2:
- Active peptic ulcer disease, recent GI bleeding/perforation, or history of peptic ulcer disease or GI bleeding 1, 2
- Advanced renal impairment or patients at risk for renal failure due to volume depletion 1, 2
- Suspected or confirmed cerebrovascular bleeding 1, 2
- Hemorrhagic diathesis, incomplete hemostasis, or high risk of bleeding 1, 2
- Coronary artery bypass graft (CABG) surgery setting 1, 2
- Labor and delivery (may adversely affect fetal circulation and inhibit uterine contractions) 1, 2
- Previous hypersensitivity to ketorolac, aspirin, or other NSAIDs 1, 2
- Aspirin/NSAID-induced asthma 3, 4
- Pregnancy 3, 4
- Current use of aspirin or other NSAIDs (cumulative risk) 1, 2
- Concomitant use with probenecid or pentoxifylline 2
- As prophylactic analgesic before any major surgery 1, 2
- Intrathecal or epidural administration 1
High-Risk Populations Requiring Extreme Caution
If ketorolac is considered in these populations, use reduced doses and careful monitoring 3, 5:
- Age ≥60 years (use 15 mg IV/IM every 6 hours instead of standard 30 mg dose) 3, 5
- Compromised fluid status or volume depletion 3, 5
- Renal impairment 3
- Concomitant nephrotoxic drugs 3, 5
- History of cardiovascular disease 5
- Significant alcohol use 5
- Concurrent anticoagulant use 5, 4
- Interstitial nephritis or papillary necrosis 3
Dosing Guidelines
Adults (Age 17-64 Years)
- Standard dose: 15-30 mg IV/IM every 6 hours 3
- Maximum daily dose: 120 mg 3
- Maximum duration: 5 days 3, 1
Elderly (≥60 Years)
Pediatric Patients
- Not indicated for use in pediatric patients per FDA labeling 2
- However, clinical guidelines support use in children with 0.5 mg/kg IV bolus, followed by 1.0 mg/kg every 6 hours or 0.17 mg/kg/h infusion (maximum 90 mg/day for 48 hours) 6
Post-Cesarean Delivery
- 30 mg IV at end of surgery, then 30 mg IV every 6 hours for 24 hours, followed by oral ibuprofen 600 mg every 6 hours 3
- Breastfeeding is not a contraindication when used as directed 3
Required Monitoring
Before initiating therapy, obtain 3, 5:
- Baseline blood pressure
- BUN and creatinine
- Liver function tests
- Complete blood count
- Fecal occult blood
For therapy exceeding 3 months (not typical for acute pain), repeat tests every 3 months 3, 5
Clinical Applications Where Ketorolac Is Effective
Ketorolac provides equivalent analgesia to morphine and meperidine for 7, 8:
- Postoperative pain after major abdominal, orthopedic, or gynecological surgery 7
- Renal colic 7, 8
- Migraine headache 7
- Musculoskeletal pain 7
- Sickle cell crisis 7
- Post-tonsillectomy pain 9
- Spinal fusion procedures (safe, does not increase pseudarthrosis risk) 3
Opioid-sparing effect: When combined with opioids, ketorolac reduces opioid requirements by 25-50% 7, 6
Critical Warnings
Gastrointestinal Risk
- Can cause peptic ulcers, GI bleeding, and perforation at any time without warning symptoms 1
- Elderly patients are at greater risk 1
- Risk increases markedly with high doses used >5 days, especially in elderly 7
Cardiovascular Risk
- Increased risk of serious cardiovascular thrombotic events, MI, and stroke 1
- Risk may occur early and increases with duration 1
Renal Risk
- Can cause acute renal failure, usually reversible upon discontinuation 7, 10
- Particular caution in patients with marginal kidney function 9
Bleeding Risk
- Inhibits platelet function reversibly 1, 6
- Bleeding time may be slightly increased 6
- Conflicting evidence regarding post-tonsillectomy bleeding, but most studies show no increased bleeding for other surgeries 6
Hypersensitivity
- Reactions range from bronchospasm to anaphylactic shock 1
- Appropriate counteractive measures must be available when administering first dose 1
Common Pitfalls to Avoid
- Never exceed 5 days of total therapy (combined IV/IM and oral) 1
- Never use in elderly without dose reduction 3, 2
- Never combine with other NSAIDs or aspirin 1, 2
- Never use as pre-emptive analgesia before major surgery 1, 2
- Do not assume faster onset than opioids—analgesic effect may be delayed 30-60 minutes 8
- Recognize that >25% of patients may exhibit little or no response 8
