Naproxen and Toradol (Ketorolac) Should Not Be Taken on the Same Day

Taking naproxen and receiving a Toradol (ketorolac) injection on the same day is contraindicated due to the increased risk of serious adverse effects, particularly gastrointestinal bleeding, renal toxicity, and cardiovascular complications. 1, 2

Why These Medications Cannot Be Combined

Shared Mechanism and Cumulative Risk

  • Both naproxen and ketorolac are nonsteroidal anti-inflammatory drugs (NSAIDs) that work through the same mechanism of inhibiting prostaglandin synthesis 1
  • Combining these medications provides no additional analgesic benefit but significantly increases the risk of adverse effects 2
  • The FDA specifically contraindicates ketorolac in patients currently receiving other NSAIDs (including naproxen) because of the cumulative risk of inducing serious NSAID-related side effects 2

Specific Risks of Combination Therapy

Gastrointestinal Complications

  • Both medications individually increase the risk of peptic ulcers, gastrointestinal bleeding, and perforation 1, 2
  • Ketorolac carries a boxed warning about gastrointestinal risks, which are amplified when combined with another NSAID 2
  • Studies have shown that elderly patients may develop gastroduodenal ulcers even after short-term use of ketorolac or naproxen 3

Renal Toxicity

  • Both medications can cause renal impairment, especially in patients with compromised fluid status or pre-existing renal insufficiency 1, 2
  • The risk of acute renal failure increases significantly when NSAIDs are used concurrently 1, 4

Cardiovascular Risks

  • NSAIDs can increase blood pressure, worsen congestive heart failure, and are associated with adverse cardiovascular events 1
  • The FDA warns that NSAID use may increase the risk of heart attack or stroke, with risk increasing at higher doses 1

Safe Alternatives

If Pain Management Is Needed

  • Use only one NSAID at a time - either naproxen OR ketorolac, but never both simultaneously 2
  • If ketorolac injection is necessary, discontinue naproxen at least 24 hours before administration 2, 4
  • Ketorolac should only be used for short-term management (up to 5 days) of moderately severe acute pain 2, 5
  • Consider acetaminophen as an alternative or adjunct that can be safely used with either NSAID (but not both) 1

For Patients Already Taking Naproxen Who Need Acute Pain Management

  • Temporarily discontinue naproxen if ketorolac is required for acute pain management 2
  • Consider opioid analgesics as a safe alternative to adding a second NSAID 1, 5
  • For migraine or acute pain, consider non-NSAID options such as triptans, antiemetics, or other adjunctive therapies 1

Special Considerations

High-Risk Populations

  • Elderly patients (≥60 years) are at particularly elevated risk for adverse effects from NSAID combinations 1, 6
  • Patients with a history of peptic ulcer disease, cardiovascular disease, or renal impairment should avoid NSAID combinations entirely 1
  • Patients on anticoagulants face significantly increased bleeding risk with any NSAID, especially combinations 1

Duration of Separation

  • If transitioning between these medications is necessary, allow at least 24 hours between discontinuing one NSAID and starting another 2, 4
  • The risk of adverse effects increases markedly when high dosages of NSAIDs are used for more than 5 days 1, 4

Remember that while each medication individually may be appropriate for pain management in certain situations, their combination provides no additional benefit but substantially increases risks of serious and potentially life-threatening complications.
