Maximum Dose of Toradol (Ketorolac)
The maximum daily dose of oral ketorolac is 40 mg per day for all adults, and the total combined duration of IV/IM and oral ketorolac must not exceed 5 days. 11
Oral Dosing (Following IV/IM Administration)
The FDA label is explicit about dosing limits based on patient characteristics 1:
For adults age 17-64 years:
- Initial dose: 20 mg PO once
- Maintenance: 10 mg every 4-6 hours as needed
- Maximum: 40 mg/day
For adults ≥65 years, renally impaired, or weight <50 kg (110 lbs):
- Initial dose: 10 mg PO once
- Maintenance: 10 mg every 4-6 hours as needed
- Maximum: 40 mg/day
Critical Dosing Restrictions
Oral ketorolac is ONLY approved as continuation therapy following IV or IM dosing—it cannot be used as initial treatment. 11 The combined duration of parenteral plus oral ketorolac cannot exceed 5 days in adults, as exceeding this increases serious adverse event risk without improving efficacy. 1
Parenteral Dosing Context
While your question focuses on maximum dose, the FDA label emphasizes that increasing ketorolac beyond 40 mg daily will not provide better pain relief but will substantially increase risks of gastrointestinal bleeding, cardiovascular events, and renal injury. 1 Research supports this—a 2023 systematic review found that lower doses (15-20 mg parenteral) provide equivalent analgesia to higher doses (≥30 mg) for acute pain 2, and a 2012 meta-analysis showed the 60 mg dose offered benefits over 30 mg for postoperative pain, but no evidence supported doses beyond this. 3
Key Safety Warnings
The 40 mg/day maximum exists because ketorolac carries boxed warnings for 1:
- Gastrointestinal risk: Peptic ulcers, bleeding, perforation (especially in elderly)
- Cardiovascular risk: MI and stroke risk increases with duration
- Renal risk: Contraindicated in advanced renal impairment
- Bleeding risk: Inhibits platelet function
Never exceed 40 mg/day oral or extend treatment beyond 5 days total (IV/IM + oral combined). Dose adjustments are mandatory—not optional—for elderly patients, those with renal impairment, or low body weight. 1
