Ketorolac vs naproxen?

Short answer: both are NSAIDs, but they’re used differently.

Key differences

- Use/purpose
- Ketorolac: very strong analgesic for short-term relief of moderate–severe acute pain (often after surgery). Not for chronic use or inflammatory conditions.
- Naproxen: milder in potency but versatile for pain with inflammation and for longer-term use (arthritis, tendinitis, menstrual cramps, general pain).

- Route and onset
- Ketorolac: usually IV or IM for rapid effect (often within minutes); sometimes oral, but less common.
- Naproxen: oral (OTC or Rx) with slower onset (30–60 minutes) but longer-lasting effects.

- Duration and limits
- Ketorolac: limited to about 5 days total of analgesia due to risk of kidney and GI problems; higher risk in older adults.
- Naproxen: can be used longer-term under supervision, with regular monitoring for GI, kidney, and cardiovascular risks.

- Potency and anti-inflammatory effect
- Ketorolac: very potent for pain relief but relatively limited anti-inflammatory benefit.
- Naproxen: good anti-inflammatory effect; useful for conditions like arthritis.

- Safety considerations
- Both: carry GI bleeding risk and kidney effects; avoid in active GI ulcers/bleeding, significant kidney disease, and in certain pregnancy situations.
Ketorolac: higher risk of kidney injury and GI complications; generally avoided for long-term use.
Naproxen: cardiovascular and GI risks exist with long-term use; generally safer for longer-term use than ketorolac but still requires caution, especially with age or existing heart/kidney issues.

Practical takeaway
- For short, severe acute pain (e.g., after surgery): ketorolac may be chosen by a clinician.
- For ongoing pain with inflammation or chronic conditions: naproxen is usually preferred, with dosing guided by a clinician.

Quick dosing notes (general, always follow a clinician or label)
- Ketorolac (adult): often 30 mg IV/IM initially, then 15 mg every 6 hours as needed; max about 120 mg/day; limit to 5 days.
- Naproxen (adult): OTC option is 220 mg every 8–12 hours, max about 660 mg/day; Rx dosing varies (common: 250–500 mg twice daily).

If you share your specific situation (what you’re treating, any kidney issues, GI problems, pregnancy status, age), I can give a more tailored comparison and help you decide what to discuss with a clinician.
