Administration Guidelines for Toradol (Ketorolac) and Ibuprofen

Critical Safety Principle: Never Combine These Medications

Do not administer ketorolac and ibuprofen concurrently or within 6-8 hours of each other, as combining NSAIDs increases gastrointestinal bleeding, renal toxicity, and cardiovascular complications without providing additional analgesic benefit. 1

Timing Requirements When Switching Between Medications

If Patient Has Taken Ibuprofen First:

Wait minimum 6-8 hours after the last ibuprofen dose before administering ketorolac 1
This waiting period allows for adequate drug clearance, as ibuprofen has a half-life of approximately 2 hours with peak levels at 1-2 hours after oral administration 1
During the waiting period, use acetaminophen or opioid analgesics as alternatives, which do not share the same toxicity profile 1

Why Combining is Dangerous:

Both are non-selective NSAIDs that inhibit cyclooxygenase (COX) enzymes 1
Their toxicities are additive rather than synergistic for analgesia 1
The fundamental approach is to avoid combining NSAIDs entirely rather than adjusting doses 1

Ketorolac (Toradol) Dosing Guidelines

Oral Ketorolac Administration:

Ketorolac tablets are ONLY indicated as continuation therapy following IV or IM dosing—never as initial treatment 2

For Adults Age 17-64 Years:

Initial oral dose: 20 mg once 2
Maintenance: 10 mg every 4-6 hours as needed 2
Maximum: 40 mg/day 2

For Adults ≥65 Years, Renally Impaired, or Weight <50 kg:

Initial oral dose: 10 mg once 2
Maintenance: 10 mg every 4-6 hours as needed 2
Maximum: 40 mg/day 2

For IV/IM Ketorolac:

15-30 mg every 6 hours (maximum 120 mg/day) for adults age 17-64 years 1

Critical Duration Limit:

Combined duration of IV/IM and oral ketorolac must not exceed 5 days in adults 2
Risk of adverse events increases significantly with prolonged therapy beyond 5 days 3

Ibuprofen Dosing Guidelines

Standard Dosing:

400-800 mg every 6 hours 4
Maximum daily dose: 2400 mg (2.4 g) 4
Use the lowest effective dose for the shortest duration consistent with treatment goals 4

Specific Indications:

Migraine headache: 400-800 mg every 6 hours, maximum 2400 mg/day 4
Back pain: 400-800 mg every 6 hours, not exceeding 2400 mg/day 4

High-Risk Populations Requiring Extreme Caution

Absolute Contraindications for Ketorolac:

History of or current risk of gastrointestinal bleeding 3
Risk of renal failure 3
Compromised hemostasis 3
Hypersensitivity to aspirin or other NSAIDs 3
Labor, delivery, and nursing 3

Increased Risk Factors for Both Medications:

Age ≥60 years: Increased risk of all NSAID-related adverse effects 1, 4
History of peptic ulcer disease: 5% risk of recurrent bleeding within 6 months even with protective measures 4
Concurrent anticoagulant use: Increases GI bleeding risk 5-6 times 1, 4
Pre-existing renal insufficiency or compromised fluid status 1
History of cardiovascular disease or hypertension 1
Significant alcohol use 1

Mandatory Monitoring Requirements

Baseline Assessment Before Starting Either Medication:

Blood pressure 1, 4
BUN and creatinine 1, 4
Liver function tests 1, 4
Complete blood count (CBC) 1, 4
Fecal occult blood 1, 4

Discontinuation Criteria (Stop Immediately If):

BUN or creatinine doubles 1, 4
Hypertension develops or worsens 1, 4
Liver function tests increase >3 times upper limit of normal 1
Any gastrointestinal bleeding occurs 1, 4

Alternative Analgesic Strategies to Avoid NSAID Stacking

Safe Alternatives During Waiting Period:

Acetaminophen: Does not contribute to NSAID-related toxicities 1
Opioid analgesics: Safe and effective alternatives that do not share the same toxicity profile 1
These can be used immediately without waiting periods when transitioning from one NSAID to another 1

Comparative Efficacy:

Ketorolac 10 mg provides superior analgesia to ibuprofen-acetaminophen combinations between hours 2-6 postoperatively 5
Intranasal ketorolac 31.5 mg is equivalent to ibuprofen 600 mg plus acetaminophen 1000 mg for acute pain 6
NSAIDs are slightly superior to acetaminophen alone for musculoskeletal pain but have more side effects 4

Common Pitfalls to Avoid

Never use oral ketorolac as initial therapy—it must follow IV/IM dosing 2
Never exceed 5 days total duration for ketorolac (combined IV/IM and oral) 2, 3
Never shorten the dosing interval below 4-6 hours for ketorolac 2
Never combine multiple NSAIDs thinking it will improve analgesia—toxicities are additive, not analgesic effects 1
Do not use in elderly patients without dose reduction (use 10 mg instead of 20 mg initial dose for ketorolac) 2
